Screw Yourself



"As regards sexual intercourse with older or younger copies of yourself, it's incest in branching or changeable timelines, and masturbation in inevitable timelines. In either case, yes, it is gay."

- tailsteak.com, "Basic Time Travel Etiquette"

It's a simple tale: Person photocopies self, or travels to an Alternate Universe, or another time. Person meets self. Both selves "make beautiful music" together. After all, what better person to be most intimate with?

Probably more prevalent in fanfiction than in original works, but it's out there. Technically, any intimacy between a character and their Enemy Without will be this. Expect much argument amongst the characters, fans, and oftentimes even both as to whether this qualifies as actual sex, incest, or masturbation.

Also known as selfcest, autoincest, or incesturbation.

In Real Life, a person who would like to do this is a true Narcissist or, in truly extreme cases, an autosexual.

Compare and contrast Opposite Sex Clone, Twincest, My Own Grampa.

Note that this is not the same as A Date with Rosie Palms.

Anime & Manga

 * Ranma One Half: Both the manga and anime explored this, though in different manners:
 * The anime Filler story, which came first, created a female-only (and demonic) copy of Ranma that tried to seduce him to steal his life force, causing him to stumble around zombie-like during the day.
 * The manga version centered on a haunted mirror, which created identical copies of whoever looked into it. Since the mirror had trapped the spirit of a girl who had longed to have a boyfriend, any resulting copies would then chase anyone of the opposite sex, and try to date them. When a mirror-copy of girl-Ranma was made, she was immediately smitten with boy-Ranma, and she tried to bed him on her very first night of existence. At the end of the story, a male clone was created accidentally, and both copies happily hooked up (since it would take another week for the seal on the mirror to be fixed, whatever they did afterwards belongs in the realm of imagination.
 * Yes! Pretty Cure 5
 * When each Pretty Cure besides Dream is forced to face an Enemy Within while wearing the Mask of Despair. Cure Lemonade faces a creepily affectionate version of her civilian self.
 * Also, a sticker set for the second season exists pairing each girl up with her implied or stated love interest: Dream with Coco and Komachi with Nuts, both of which became canon in season one; Karen with Milk, which can't be outright stated but is pretty darn close; Urara and Rin with Syrup, both of which are currently implied (but Urara seems to be winning, despite Toei earlier saying otherwise... Rin has bad luck with boys, doesn't she?), and Kurumi with... Milk again. Herself. Yeah.
 * Happens in the second episode of Kaiba; the woman who helped the title character sneak onboard a spaceship copies her own memories into his body and the two of them have a little fun together... which is quite disturbing given the series' surreal and childlike artstyle. Then the copy kills the original for fear of being deleted.
 * Technically, the implied attraction between Madlax and would be this, seeing how she is her.
 * In Hentai manga Alice in Sexland, an artisan created a cupboard that can spawn a perfect Hermaphrodite (and perfectly horny) clone of its female user.
 * Katekyo Hitman Reborn
 * The relationship between Mukuro and Chrome tends to feel like this. Their names are actually anagrams of each other (in Japanese "chrome" is pronounced "kuromu"), and they look incredibly similar (other than the gender difference), coupled with the fact that they share a body...
 * Most people think Tsuna and Kyoko are the closest thing to this without really being related.
 * Closely related: Jail Scaglietti of Magical Girl Lyrical Nanoha impregnated Uno, who was revealed in the third StrikerS Sound Stage to be his Opposite Sex Clone. Of course, he likely did it in a scientific way, but the lack of information on how he specifically did it inspired some theories that are more base. Of course, he did this with all the rest of his cyborg "daughters" too. It's just that Uno is the only one that's an Opposite Sex Clone.
 * Patalliro of Boku Patalliro! has molested and been molested by nearly identical Patalliros of the distant past and future. Presumably they are both ancestors and descendants of the main Patalliro. Let that sink in.
 * In Beat Angel Escalayer, Sayuka gets raped by
 * Sailor Moon
 * Okay, it never got to "screwing", but in the manga
 * Neo Queen Serenity was also pretty excited to see her past self....
 * In Kaguya Hime, a few characters express interest in the bodies of their clones, but that's (probably) usually because they need their organs. Julian, though, is definitely very interested in his clone Miller; among other things, he mentions having seen an almost-unnoticeable scar on Miller's body during a sex scene in one of the films Miller played in, and later does something that was either nuzzling his face very tenderly, or kissing him (darn you, Discretion Shot). Not to mention the reason he wanted to find Miller in the first place.
 * The last (non-canon) episode of Kämpfer ends with the gender-swapping protagonist married to him/herself. And he/she/they had a child.
 * The Yuri one-shot, Endless Narcissus, is about a girl who loves herself so much she goes and gets a clone of herself.
 * The Inspectors anime of Super Robot Wars Original Generation has Alfimi kissing Excellen while her clothes start disintegrating.
 * The Bait and Switch Credits of Puella Magi Madoka Magica feature a Transformation Sequence in which a pair of naked Madokas get extremely cuddly with each other. This might be the only time you'll see a Magical Girl get dressed via symmetrical docking.
 * Bondage Fairies: Fairies are apparently so narcissistic, they will do their own reflections... which turns out to be a bad thing, since.
 * Invoked in Macross Frontier Sayonara no Tsubasa where part of Sheryl's on stage performances involve her being seduced by herself (or rather a holographic projection of herself, often times in male clothing).
 * The opening of Lupin III: The Woman Called Fujiko Mine ends with two Fujikos making out.
 * In the final volume of Devilman Lady

Comedy

 * In one bit, stand-up comedian David Cross jokes about this guy at the gym fantasizing about pulling himself out of the mirror, and the two thems dance to Barbra Streisand music, make out, and then "they fuck each-other on the Flexinator 500!"
 * The basic premise of this sketch by the The Whitest Kids U' Know.
 * In a broadly similar vein, Woody Allen once quipped: "I love to masturbate. It's sex with someone I love."
 * A common joke: "My own clone! Now neither of us will be virgins!"
 * In one of Jim Gaffigan's specials, he says couldn't have sex with another man, "unless he looked like me." "Jim-on-Jim" action, indeed.

Comic Books
"Ultimate Spider-Woman: For the record, I'd regard it as masturbation. Just saying."
 * Jamie Madrox (a second-string X-affiliated character) has the power of self-duplication, which allows him to split into multiple physical copies of himself, sometimes with distinct personalities. Guess what trope comes up in about 90% of Madrox-related Fanfic. One of Madrox's duplicates brings out the subject when he's sitting bored at a bar. He indicates he'd rather continue to be bored.
 * An unusually blatant example, The Sentry and the Void are both alter-egoes of the same man, split into two bodies, who have passionately kissed on at least one occasion.
 * XXXenophile delved into the trope more than once, with stories titled "Self Indulgence" and "Dopplegangbang", clones in "Family Reunion", and a situation in "Heart of Stone" where a cleric has to turn two of her fellow party members into illusionary duplicates of herself in order to satisfy the conditions of a curse.
 * Once he discovers that is, Finder's Magri White declares that he can do as he pleases with him, and proceeds to play tonsil hockey with him.
 * In Cerebus, the title character learns about halfway through the series that he is a hermaphrodite whose genital arrangement could have led to him impregnating himself if his uterus had not been permanently damaged when he was a child.
 * Deadpool recently went into another dimension where he encountered a female version of himself and they made out. He then declares Squick.
 * In Little Ego (an erotic parody of Little Nemo), Ego has a dream where her reflection steps out of the mirror and starts to have sex with her. Then the reflections of both of them step out of the mirror and join them. And then the reflections of all four. And then she wakes up.
 * In Green Lantern comics, the title character's girlfriend, Carol Ferris, was once possessed by a creature made entirely out of love called the Predator. He gave her a Literal Split Personality, in this case separating her masculine side from her feminine side. His ultimate plan was to achieve this trope, but it didn't work out, largely because the male version of Carol turned out to be a creepy stalker.
 * The Ultimate Spider-Man version of Spider-Woman is a female clone of Peter Parker who has all of his memories. As she and Peter are about to part ways, the two of them share an "awkward hug".


 * This may not be a literal application of the trope, but when Most Excellent Super-bat of the Super Young Team met a young woman cosplaying as him, he felt he couldn't pass up the opportunity to get with her. He claims it was the simple fact that there are people out there who practically worship him that got him so turned on, but it's hard to not see it as an exercise in narcissism.
 * In the 2011 Dollhouse Epitaphs mini-series, an Ivy imprint in a male body and an Ivy imprint in a female body are seen hooking up, though Alpha (with whom the Ivy imprints are trying to raise an anti-Rossum army) interrupts them before they can get fully undressed.

Fan Works
"Comments: can't be this psychological."
 * Pick a film/TV series. Guaranteed there's at least one fic out there of a character screwing a different character that actor has played. Which is sort of like screwing yourself.
 * Star Trek Voyager
 * The fandom wound up with this due to the actor for Tom Paris having been on Next Generation as an entirely different character. So a lot of fanfic winds up with the two characters meeting up in some bar, drunk. (Or, alternatively, just doing a Recycled Script of someone else's fic with Tom being such a narcissist he heads to the holodeck to copy himself.)
 * Then there is all the times Voyager crewpeople have met duplicates of themselves. Or not met the duplicates of themselves. They really do give the actors lots of roles to play.
 * There are tons of Jackson Rippner/Jonathan Crane fics out there; Cillian Murphy on Cillian Murphy action. At least one person has actually thrown Jim from 28 Days Later (also played by Murphy) into it...
 * Doctor Who
 * There's an R-rated Ninth Doctor×Claude Rains fic out there (both played by Christopher Eccleston). It is... surreal.
 * As well as quite a few Tenth Doctor×Casanova tales. Although this was pretty much inevitable, considering the actor in question.
 * Although never even hinted at in-series, the use of "regeneration" in Doctor Who and the propensity for the Doctor to meet his past selves has all the inevitable implications. There is even an entire livejournal community dedicated to exactly this.
 * Ladies and gentlemen, I give you Harry Potter!Helena Bonham Carter × Sweeney Todd!Helena Bonham Carter.
 * Any character with a split personality (especially where the other half is a Bishonen), such as H/Allelujah from Mobile Suit Gundam 00, D.N.Angel or Yu-Gi-Oh, will be given this treatment in some niche of whatever fandom the character appears in. Explicitly, said "characters" in one body (like Allelujah and Hallelujah) will instead be two separate characters all together, and... will make music together. And this is not restricted to anime.
 * Especially Yu-Gi-Oh Perhaps the most popular pairing in the fandom is Yugi and Yami. Add in Yami's past self Atem for a threesome. There's also Bakura and "Ryo", and Marik and "Malik", fanon names for the evil and good sides of the characters. Kaiba and Set (his past self) is also popular.
 * The Yu-Gi-Oh GX fandom has something called Monochromeshipping, which pairs up Season 3 Manjuome Jun with... Season 2 Manjoume Jun (however, in most fanfiction, whatever happens between the two Juns happens purely in his head.) Judai×Haou and Johan×Possesed!Johan are also fairly common.
 * Katekyo Hitman Reborn
 * Besides canon (see above), there are all those fanworks that pair up the boys with their "ten years later" versions of themselves... there's even official art of the characters together with their older selves. Undoubtedly there's also a fanart/fic pairing the cast with the first generation of Vongola family. Who look almost exactly like the tenth generation.
 * Pairing the hero Tsuna in Hyper Dying Will Mode with Tsuna in his normal state is far from uncommon.
 * It's an old question in Legion of Super-Heroes fandom whether Triplicate Girl sleeping with herselves would be incest or masturbation...
 * Lavi and Deak from D Gray Man. Also, . And I've actually seen a fic where Allen was paired with his innocence.
 * The title character of Naruto is technically able to create a clone of himself -- of the opposite gender to top -- and the fans haven't ignored its potential. It's called the Harem Jutsu for a reason.
 * Ranma One Half lemon fics use this with Ranma's male and female sides. Some would say far too often; others would say not often enough.
 * And it's not always strictly with Ranma(s); for example, there is this lemon fanfiction entirely about this trope: Narcissism.
 * There is one Mind Screw fanfic where it is revealed that, thanks to some Time Travel, Ranma is both is own father and his own mother....
 * There's two actually. One where he's actually both Genma and Nodoka... and another where he gives himself up for adoption to the Saotomes.
 * This can be argued as the case of the fanshipping of Luc and Sasarai in Suikoden. While they are in most ways Different As Night and Day in terms of personality and their Canon relationship more closely resembles the Cain and Abel, the fact that they are cloned Artificial Humans of their father means that they are genetically identical, making any pairing with them riding the line with this trope.
 * Youko Kurama×Shuuichi Kurama is seen occasionally in Yu Yu Hakusho fanfic, but they're not usually portrayed as the same person.
 * There is a really bizarre (pun completely intended) Jo Jos Bizarre Adventure lemon which included Will×Gyro and Jonathan×Johnny pairings. May or may not count though as Gyro and Johnny are their alternate universe incarnations, but look and act very different.
 * Star Trek
 * There's William T. Riker's transporter clone W. Thomas Riker, who has the advantages of being A) one of the vanishingly rare Star Trek duplicates who is not remerged, killed, or returned to his home universe at the end of the episode, and B) Jonathan Frakes.
 * Goatee!Spock from the Mirror Universe is the other major example of a duplicate character left kicking around after his episode. Considering that Spock is one half of the pairing that originated the term Slash...
 * Not to mention Nu!Spock×Spock Prime on the Star Trek Kink Meme. Oh, yes, it's happened. But after all, this is the kink meme we're talking about. There is also Nu!Kirk×Kirk Prime, and possibly others, but the two Spocks do have the advantage of already being in the same universe.
 * Supergirl has an alternate-universe doppelganger named Power Girl, who is basically her, only ten years older and more aggressively individualistic (she doesn't wear Superman's costume), with shorter hair and... well, if you've ever heard of the character, you know what else. There is a(n un)surprising amount of Supergirl×Power Girl slashfic.
 * Haruhi Suzumiya
 * Various doujins of The Melancholy of Haruhi Suzumiya have this. Specifically, Mikuru and her future self, with some help from Kyon.
 * Pairing the characters with their Suzumiya Haruhi no Seitenkan counterparts is surprisingly common, with Kyon and Kyonko being by far the most favorite.
 * One of the well-known example is Tea of Sagittarius series, where the original Kyon is accidentally genderbent into a female version, . Long short story, Haruhi unconsciously summons male Kyon from another world as well. Regadless, out of curiousity, pride, and self denial they began to explore the world of sexual perversion in secret, taking advantage of their current state and both insist that this would count as masturbation instead. It wouldn't be so bad if this ISN'T about Kyon & Kyonko we're talking about, as someone commented:


 * In Kyon: Big Damn Hero, Kyon has a dream involving Mikuru and Adult!Mikuru but stops thinking about it before it goes into any detail.
 * Danny Phantom
 * Somehow, there are Danny Fenton×Danny Phantom pairing fan-works, even though it's impossible because he's one person... Unless you count the thing with the dream catcher that can split him into two halves twice.
 * Then, of course, there's also Danny×Dani...
 * And his future self. Yes, that future self. Before you think about that too hard, there is an actual fic for that: Narcissism. It's quite horrifying, and sadly a Dead Fic.
 * There's always the fact that one of his powers is actually creating duplicates of himself. And yes, one of the duplicates can go back to human with the other staying as ghost. Granted only Vlad and his Bad Future self did that, but it's only a matter of training for Danny to do it.
 * Oddly, Ineffectual Sympathetic Villain and Draco in Leather Pants Vlad -- who can duplicate and has been portrayed as somewhat vain -- evades this treatment.
 * The World Ends With You has attracted a lot of this, thanks to the implication that there are alternate universes that may be crossed.
 * Members of the Tales of the Abyss fandom have taken the implications of replicas to its logical conclusion.
 * While the prospect doesn't exist, the fandom of To Love Ru continues to clamor for an actual Opposite Sex Clone conveniently given a place in the male protagonist's Harem, due to his . Then again, because of the female protagonist's status as a Gadgeteer Genius, the likelihood of this happening isn't so far out...
 * Super Robot Wars
 * Super Robot Wars Reversal gives players the choice of either playing as Raul or Fiona Gureden, who's really the same person. Plenty of fanworks used this trope, but when they were brought into the Super Robot Wars Original Generation sub-series as Half-Identical Twins, it became Brother-Sister Incest.
 * Kazuma Ardygun and of Super Robot Wars W, the latter being his Opposite Sex Clone created by The Database. Since Kazuma holds the dubious honor of being the first Original Generation in the franchise not to wind up with a Love Interest, doujin and fan artists had a field day with this trope by pairing them together.
 * Ever since Tomb Raider: Underworld, there's been an increasing number of pics with Lara and her Doppleganger from that game.
 * This Gargoyles fanfic features multiple clones of Anton Sevarius, some of them gender-swapped, and the daughter that one pair among them decided to create the old-fashioned way as an experiment. (Note that this story occurs more than halfway through an extensive fanfic continuity.)
 * Pokémon
 * There's at least one doppleganger shipping: between Ash and a cross-dressed Ash and the pseudo-example of malevolent shipping: Ash and the king of Pokélantis, who takes Ash's form.
 * Depending on your viewpoint, either Kotone from Pokémon is based off Kris (she technically never had a canon name) or she is a redesigned Kris. However Kotone×Kris is a popular pairing.
 * That Guy With The Glasses
 * In the fandom, both Nostalgia Critic×Ask That Guy and Spoony×Dr. Insano are extremely popular. For the former, dub-con and Mind Rape are pretty much par for the course (it's also been made into incest) and while the latter isn't so bad because of Insano's woobie-dom, it's usually presented as innately creepy.
 * And Linkara×Mechakara. As you can probably tell from how Mechakara is in canon, it's also insanely disturbing. Technically
 * One Sailor Moon fanartist and fanfiction writer, Bill K., lets Sailor Pluto have some fun this way, with several time-traveling future selves.
 * The Kingdom Hearts series has a strangely huge potential for this (and don't think for a second fandom hasn't picked up on this), with Riku and the Riku Replica, Demyx and his waterclones, Xemnas and Xehanort's Heartless (heck, why not Xehanort himself?), Roxas and Sora, Kairi and Namine, and most recently, Sora and . And Roxas and . And Sora, Roxas, and, for a threesome of selfcest.
 * There is a good chance the whole Roxas, thing could go even further with Ven, who undoubtedly is in some way "the same being" as, given his appearance and voice being absolutely identical to Roxas'. So now we have  potential, although this assumes they can all co-exist, but we don't know yet for sure if that can potentially happen.
 * There's also the innumerable stories and drawings which pair the Squaresoft Expies from Kingdom Hearts with their original inspirations.
 * Just for a compelte list: the past and present versions of Mickey and Pete, Vexen and Vexen Replica(s), Sora and Anti-Sora, Roxas and Shadow Roxas, Donald, Goofy and Sora's Master Form (technically), Roxas and Ven, Vanitas and Ven, the real and virtual versions of Hayner, Pence, Olette, Seifer, Vivi, Fuu, Rai, Setzer and Kingdom Hearts itself. In Final Mix, there's the real and virtual versions of everyone in Organization XIII, and Larxene and Zexion's copies...
 * Ace Attorney series:
 * Diego Armando×Godot. The game had some people believe that Diego and Godot are twins, at least before the reveal. The obvious difference in their looks was explained with partial albinism, which is known to cause problems with eyesight along with the obvious white hair. And as no-one knew what colour Godot's eyes were and fangirls are prone on jumping the gun...
 * On a more lighter side, but still pretty creepy, is fanart of crossovers between the US and Japanese counterparts. Phoenix (US) seems to be always portrayed as enjoying Ryuichi's (JPN) company a little TOO much...
 * And all the . There's even a popular dôjinshi devoted to them gang-banging Edgeworth.
 * Mia. Original, Maya-style or Pearl-style. The third iteration gets a little creepy when one remembers that the channeler is a pre-schooler.
 * And in the grand tradition of people × their alternate identities, we now have
 * Those watching the Takarazuka musical often ship Miles Edgeworth×The Miles Edgeworth Backup Dancers, all of whom dress and look exactly like him.
 * Phoenix, Hobo Phoenix and Feenie. Sometimes they also throw Kid Nick into the mix.
 * The Legend of Zelda
 * ''Sheik×Zelda is popular. Tetra×Zelda, less so for some reason. Tetra×Sheik practically doesn't exist (and technically doesn't count).
 * On the other hand, surprisingly little The Legend of Zelda Four Swords hentai exists. But why write selfcest when the official manga itself is already catering to the pairing (Red×Blue Link, to be specific)? Freud would love to read that one.
 * Dark Link and regular Link (of any game/universe) are paired together so often it long ago stopped being funny.
 * There is fanart of Wind Waker Link and young Ocarina of Time Link. Also of Twilight Princess Link and adult Ocarina of time Link. And for the ones who want to cross over to Shotacon territory, there's always a combination of the two... including both versions of Ocarina of Time Link together. However, the only one of those that is Screw Yourself is the Ocarina of Time Links, as the others are just expies, identical great-great-(etc)-grandson, or Generation Xerox.
 * The 2012 movie version of The Lorax just opened into theaters less than a month ago, and already the internet is swarmed with fanart/fanfiction/fanWHATEVER between the Young!Once-ler and The Onceler, nicknamed "The Greedler" (after he becomes successful). The cute little pairing name for it? Oncest.
 * There is a hella lot of Prince×Dark Prince from Prince of Persia: The Two Thrones.
 * In Tales of the Abyss we have Asch and Luke. There are plenty of fanfics pairing them together. And then there's ... Fandom has affectionately dubbed this particular brand of Screw Yourself "Replicacest."
 * Breath of Fire IV (unsurprisingly) has a prodigious amount of fanart and fanfic -- to the point that this pairing has earned not one but two Fan Nicknames: . This is only encouraged by the fact that the two are a Literal Split Personality and that there is a manga adaptation ongoing in the same manga magazine running Vassalord. By the same company that was responsible for Peacemaker Kurogane. If this isn't brain-breaking enough,
 * Courtesy of his visit to the post-apocalyptic future, Dean Winchester of Supernatural gets this in fics, both in the form of Dean×future!Dean and Dean×future!Dean×future!Castiel.
 * Mega Man
 * The Japanese Mega Man Star Force fandom is full of Pat×Ray fanarts.
 * Classic has Gemini Man, a narcissist with the ability to clone himself. The implications aren't lost on fandom.
 * Meanwhile, the Vent×Alie pairing was fairly popular for Mega Man ZX, before Advent came out. The jury is still out on whether that counts as this trope or Brother-Sister Incest.
 * This works with Alternate Continuites too. There exists some fanart pairing the original Lovely Angels with their Dirty Pair Flah counterparts. Sometimes adding the Adam Warren versions for variety.
 * Flippy×Flippy is surprisingly popular within the Happy Tree Friends fandom.
 * Vocaloid fanfiction and fanart tends to use this trope, mainly because the fandom likes creating Opposite Sex Clones of the official characters. A favorite pairing is Len×Rin, which tends to overlap this with Brother-Sister Incest. And even they have their own fanmade gender-swapped clones.
 * Harry Potter
 * There has been several fics involving Hermione, um, misusing the Time Turner in this manner.
 * Don't forget polyjuice potion. "Hey, Hermione, give me a strand of your hair..."
 * The Wizards of Waverly Place fic ''Selfportrait has Alex having sex with a doppelganger she created in order to paint a portrait of herself.
 * Power Rangers
 * In many, many, MANY Power Rangers SPD fics, the fact that Z can create duplicates comes to the fore for just such a reason.
 * Tommy Oliver is sometimes paired with his clone/ancestor Tom. There's even a few fics that are threesomes of Tommy, Tom, and the White Stranger.
 * Death Note fandom has a small but dedicated contingent which ships Kira Light with, in an Enemy Within-style thing.
 * Axis Powers Hetalia: Himaruya's liberal use of opposite-gender counterparts and AUs in his own work, along with the possible nature of civil wars and so on, has led to some selfcest fics.
 * In one Calvin and Hobbes arc involving time travel, Calvin and his future self both end up taking off in the time machine leaving two Hobbeses alone. There's at least one comic floating around the Internet that... um... focuses on what they get up to in the meantime. Brain Bleach is mandatory.
 * Even Mother 3 isn't safe from this.
 * Neon Genesis Evangelion
 * Rei Ayanami has a few dozen identical clones of herself stored in an LCL tank. She is the resident Innocent Fanservice Girl and Memetic Sex God. This has lots of potential...
 * There is a fic (NGE: Bloodlust, chapter four) including a scene where a clone vampirificates another and the two celebrate the occasion by playing with each other.
 * And another one where Rei gets bored during class and starts fantasizing about her being replaced by one of her clones without her being told about it. Since one of them has to be eliminated, they hold a lesbian version of a last supper...
 * There's less of this from Touhou fandom than one would expect from a fandom full of Self Fanservice.
 * What does exist involves interaction between counterparts from PC-98 and Windows continuities, the canon doppelgangers in Phantasmagoria of Dim. Dream, and the characters who can use body doubles to attack (especially Yuuka and Flandre). Or Yukari could just be fooling around again.
 * Youmu (a half-ghost with a one human and one ghost body) can pull it off with or without magic, and it's been done to various degrees. And remember, in canon her ghost half can be altered into a copy of her human half. We will leave the rest to your imaginations.
 * Nebula Nostrum, an Artemis Fowl fanfic that features Opal×Lili×Opal×Lili, essentially making it a slash clonecest love quadrilateral.
 * Professor Layton rarely (since the ship has a Shotacon nature) but still has the two Lukes of the third game, the little!Luke who is familiar to anyone who keeps up with the series, and his future self: big!Luke.
 * My Little Pony Friendship Is Magic
 * From the fandom, we have Pinkie/Pinkamena. There's also a fanfic, On A Cross And Arrow, features the Mane Six travelling to an alternate universe where everyone who's female is male and vice versa, and features Fluttershy and Rarity falling for their male counterparts. Also heavily implied to be the case between Princess Celestia and her counterpart Prince Solaris.
 * There's a considerable amount of fan art and fan fiction that turns Trixie's narcissism as seen in the show Up to Eleven. Much of it involves either Trixie fantasizing about herself with the aid of a mirror or using clones produced through magic, but in one parody fanfic she ended up having a 5-way with her reflection, a clone, a future version of herself, and a robot with her likeness. And to further complicate things, the story closed with a male version of her from a parallel universe walking in.
 * Sonic the Hedgehog: One of the infamous Robotnik comics from That One Imageboard features this.
 * Persona
 * Persona 4 fandom: Shadow-on-human action? There's a pretty huge chunk of Yaoi Fangirls who will slash Yosuke with himself, or Kanji with his Armoured Closet Gay, or Teddie with his nihilism, or even the MC with his shadow, though he never had one... And, of course, people with other people's shadows, or others' shadows AND the human, out of some forced yet plausible Twin Threesome Fantasys. This all applies to the girls too (such as Chie and Dominatrix Bananahead), but it's just more prominent among Yaoi Fangirls. On second thought, it's not so much screwing themselves rather than aspects of themselves... but we'll save the philosophical implications for another day.
 * Naoto×Shadow Naoto is one of the more popular Human×Shadow pairings.
 * And its predecessor Persona 3's most popular yaoi pairing is Minato×Ryoji. . This also applies for Ryoji×Female Protagonist shippers.
 * Since her creation in Phase 3 of Gorillaz, Cyborg!Noodle has naturally appeared in fanarts where she's making out with Real!Noodle.
 * When Dante in Devil May Cry 3 gained the Doppleganger ability, it gave the fangirls an excuse to do this. Not that Dante didn't have enough problems already, given that he has Vergil pestering him.
 * Starcraft: An artist on Deviant ART was badgered into producing this image involving Zergified!Kerrigan and Terran!Kerrigan. For all intents and purposes she seems quite disturbed by having actually drawn it.
 * If we assume that in Bleach, the Inner Hollow is a part of a shinigami's soul, Ichigo×Hichigo pairing is basically this. The same goes for shipping any shinigami with his or her zanpaktou.
 * Team Fortress 2, having two teams only seperate in team colour, is naturally rife with this. For some reason Scout is the one who gets it worst.
 * From Dragonball Z, there is Future Bulma×Bulma as well as Future Trunks×Trunks. Both pairings are technically possible in-universe, thanks to Bulma being a genius and inventing a time-machine.
 * Anders from Dragon Age II is sometimes paired with his Super-Powered Evil Side, Justice/Vengeance.
 * While Elliot and his Opposite Sex Clone Ellen from El Goonish Shive would rather avoid thinking about it in the webcomic, there are naturally Rule 34 pics of them together.

Films -- Animation

 * In The Nightmare Before Christmas, Dr. Finklestein ends up creating what appears to be a wife that looks exactly like him, even sharing half of his brain. This naturally lends fuel to the Alternative Character Interpretation that Dr. Finklestein created Sally for more carnal desires.

Films -- Live-Action
"Austin: Paging Dr. Freud!"
 * In Click, when where introduced to the year 2017, a newscast can be heard in the background stating that: "Michael Jackson, the first man to clone himself, is suing himself for molesting himself."
 * A deleted scene in Austin Powers: The Spy Who Shagged Me has Number 2 from the past and future in bed, smoking cigarettes, and the older one musing that it's not technically cheating. This is based on the gag actually used at the end of the movie, with two temporally displaced versions of Austin ending up in bed with his Love Interest.

"Kirk: I can't believe I kissed you!
 * Star Trek VI the Undiscovered Country: Kirk to fellow Klingon-gulag inmate Martia, who turns out to be a shapeshifter, formerly in the form of an attractive female humanoid and now in the form of Kirk himself:

Martia: Must have been your lifelong ambition!"


 * A bit of Adam Westing in there for William Shatner, playing off his perceived enormous ego.

"Jack: I've always wanted to do that."
 * In The 6th Day, Adam Gibson, who was cloned without his knowledge, tells the villain he should clone himself while he's still alive. The villain asks if it would be so he could get Adam's unique perspective. Adam says, "No, so you can go screw yourself." (and when the dead villain falls over an unconscious/incomplete clone of himself, Adam's reply is "When I said you should screw yourself, I didn't mean it literally.")
 * The John Waters movie Female Trouble stars a character played by Divine who gets raped and impregnated by a man... who is also played by Divine. She ends up homeless and she calls her baby daddy for help.
 * In several film adaptations of The Strange Case of Doctor Jekyll and Mr. Hyde, Jekyll and Hyde hallucinate each other and so are able to interact. Usually they fight or argue, but sometimes their actions can get a bit... suggestive. Rather appropriate given that one of the possible literary interpretations of the book is as an allegory to the double life that was necessary for Victorian-era gay men.
 * The 2002 John Hannah adaptation is a prime example of this, with Hyde often getting intimately close to Jekyll, and even licking him on the cheek at one point, and in the 2008 film starring Dougray Scott, at one point Hyde pins Jekyll to the wall and kisses him. That's the farthest that any movie adaptation has ventured to go, but several fanfiction works have taken this idea even further.
 * The fourth Pirates of the Caribbean movie, On Stranger Tides, has Jack Sparrow kiss someone disguised as him.

Literature

 * The Man Who Folded Himself by David Gerrold. The eponymous time traveler has sex with both male and female versions of himself, sometimes several at a time.
 * All You Zombies by Robert A. Heinlein.
 * Heinlein's Time Enough for Love: Lazarus Long at first objects to screwing his own identical-twin female clones, but relents when they assure him it's no more than "Narcissus loving himself."
 * Downtiming the Night Side, by Jack Chalker. Not as squicky as it sounds: By the time the hero/heroine hooks up with him/herself they are essentially different people thanks to a Gender Bender, several time loops and the side effects of the book's time travel Phlebotinum.
 * F.M. Busby wrote a short story with a similar concept using Reincarnation instead of a Gender Bender. The hero dies and finds himself reborn in the past as the girl who will eventually become his beloved wife. He/she then gets to re-experience their life together from her perspective, eventually giving birth to a daughter who turns out to be (surprise, surprise) him/herself yet again, reborn once more into the past.
 * Fifteen-year-old Henry finds an outlet for his pubescent sexual urges this way (and, it's implied, repeatedly) in The Time Traveler's Wife. For added fun, his father walks into the room and catches him (them?) in flagrante. Henry rationalizes having gay sex with himself as a parallel to masturbation, and the obvious course of action that "anyone" would take in his situation (thankfully, his eponymous wife never needs to hear about it). Note that possibly they were only jerking each other off. And the father walks in on them post whatever-happened, although it was still totally obvious to him that it was something sexual.
 * Parallelities by Alan Dean Foster not only has the main character bedding an alternate female version of himself while traveling through The Multiverse, he eventually finds an alternate Earth populated entirely by doubles of himself.
 * The Darkover novel Two to Conquer has the main character meet up with an exact physical duplicate of himself. The expected interaction occurs.
 * Stork Naked, by Piers Anthony.
 * Sex with Ghosts, by Sarah Kanning.
 * While the book doesn't get that far, in Magyk by Design by Esther Friesner, a cat (talking, magical) named Scandal gets split up into a number of copies by villains (who can control the copies). By the end of the book, he reabsorbs them. Except for the one representing his female side, who being just a kitten was useless to them and out of the fight. He's accelerating her maturation, for this trope's purpose, with her full encouragement. (They are the only two cats in this world...)
 * Nine Lives, an early Ursula K. Le Guin story, has a set of ten clones, five male and five female, who join some place where there were already two normal people working. When the clones have sex with each other, one of the non-clones says, "Oh, let them have their damned incest!" and the other says, "Incest or masturbation?" (The clone-sex wasn't a major plot point, just a part of showing how the clone-group couldn't relate properly to outsiders.)
 * A similar case of clone incest appears in John Varley's Titan, where the lab-cloned Polo sisters privately engage in behavior that's still illegal in Alabama.
 * Varley's stories have often had this, including The Phantom of Kansas.
 * Used romantically with several pairings amongst the Starfish Characters in Scorpion Shards. They are soul mates, so to speak, but it gets a little weird when one of them realizes he can't fall in love with someone who isn't part of the group.
 * The main character in James Alan Gardner's Commitment Hour spends the last few chapters of the book . To make matters worse, . The end of the book.
 * In Fred Pohl's The Coming of the Quantum Cats, similar characters from a mulititude of timelines mix & match during a cross-time war; when a slightly more advanced timeline decides to quarantine the others to avoid eddies in the space time continuum, a lot of editions get dumped on an uninhabited Earth, where multiple copies of a particularly unsavory mook decide to set up house together.
 * In With a Tangled Skein, Niobe kisses two alternate timeline versions of herself. Clearly justified, as Niobe is essentially described repeatedly as the most beautiful woman of her generation.
 * The short story "Blood Sisters" by Joe Haldeman involved the Mafia cloning a young heiress in order to substitute the clone and get the inheritance. The clone didn't want any part of the plan -- she thought of the original as her mother and didn't want her murdered -- and went to a private detective to ask for help hiding from the Mob. When she finally met the heiress, however, the mutual attraction was strong enough to overcome any qualms about being intimate with her mother. The detective comments, "I did wonder what you would call what they were doing. Was it a weird kind of incest? Transcendental masturbation?" At the end of the story, it's mentioned that original and clone openly being lovers "started a fad among the wealthy, being the first new sexual diversion since the invention of the vibrator."
 * A strange case in Sergey Lukyanenko's Autumn Visits, where Anna has a "shower moment" with her not-quite-human duplicate Mary. It's not specified exactly what they do in the shower, but their mutual attraction is clear, although Anna's attraction is mostly due to religious fervor (she believes Mary to be God).
 * Isaac Asimov wrote a parody of "Home on the Range" called "Home with my Clone" ("...with the Y chromosome turned to X.")

Live-Action TV
"Arlene Rimmer: How could you possibly contemplate making love to yourself?
 * Red Dwarf
 * In "Parallel Universe", the crew goes to a parallel Red Dwarf where humans are all of opposite genders, and Lister gets drunk and sleeps with his female self, to the disgust of both versions of Rimmer.

Arnold Rimmer: Well, why break the habit of a lifetime?"

"Rimmer: This of course created the most enormous moral dilemma. Technically, she would be my sister, and therefore unable to take me as her lover. After much soul searching, I reluctantly decided, "What the hell", I just wouldn't tell her."
 * Of course, Arlene Rimmer was also trying to come on to Arnold Rimmer, using (or planning on using) the same crappy pick-up lines and talent for hypnosis he mentioned at the beginning of the episode... she was also planning on showing him some Guy on Guy porn she owned in the hopes it would "loosen him up".
 * The parallel universe has male and female roles completely switched, so Deb Lister gets Dave Lister pregnant. This is revealed immediately before the end of the episode, and what happens to the fetus is dealt with in some fast scrolling text at the start of the following season....
 * In this same storyline, the Cat is very excited to meet his female opposite and is clearly planning to have sex with her. "If you hear me screaming, do not, I repeat, DO NOT come to the rescue!" Of course, his opposite turns out to be.
 * Ironically, in "Rimmerworld", he decides to make an Opposite Sex Clone of himself... somehow. And then have sex with the clone, despite some misgivings:

"Cat:
 * However, the resulting does not, and goes on to eventually  Even more disturbing is the fact that  which really isn't any better.
 * In the episode "Camille", they met a Gelf who appeared to each character as their "perfect companion", which everyone assumed to be their perfect female companions. Predictably, Lister saw Kochanski (or rather, Kochanski if she was a bit more like him, including Scouse accent); slightly less predictably, Rimmer saw a fairly plain, underachieving hologram; and Kryten saw a robot which looked very similar to him (because they're from the same series, series 4000), but had a distinctive personality and looked slightly more feminine. The Cat, after much excitement, finally sees

Gelf : Can you think of anyone more deserving?

Cat: Well, when you put it like that, I guess not!"

"Willow: I'm so evil, and skanky... And I think I'm kinda gay!"
 * Perversions of Science used this concept. A man decides that no woman is good enough for him, so he decides to create "the perfect woman" by having a sex change and then going back in time to have sex with himself.
 * A skit on The Man Show had Adam Corolla and a clone of himself, eventually coming to the conclusion "After all, it's only me, right?"
 * Buffy the Vampire Slayer
 * Willow's Lesbian Vampire Evil Twin acted interested in getting physical with her human counterpart, licking the squicked-out Willow with lustful intent.

"Topher: She's got me locked out on this end.
 * This was also brought up in the episode where Xander was split into two Xanders, though the comment was about a threesome with them and Anya. The other Xander in that scene was being played by Nicolas Brendan's identical twin brother, so there could have been some Twincest there as well.
 * Well, Alex from Wizards of Waverly Place doesn't meet herself and make beautiful music, but she still falls in love with herself when she drinks both halves of a love potion. The bad part is that her head gets big whenever she compliments herself... literally big.
 * When he is forced to accompany Adelle to the Washington DC Dollhouse, Topher imprints Victor, a blank active, with his own personality in order to mind the shop in LA. This leads to the following exchange over the phone:

Victor!Topher: Who's your back door man?

Topher: We'll pretend I didn't say that.

Victor!Topher: Yeah."

"Amy 1: Do I really look like that?
 * One of the ways the illusion-casting Candice from Heroes tries seducing Sylar is by appearing to him as Sylar. ("Or something more familiar... if that's what you're into.")
 * Subverted on Scrubs: J.D. thinks that his girlfriend, Dani, moaned her own name during sex, but it was actually the guy she was seeing at the time, whose name is Danny. He's also the Soup Nazi.
 * In Sliders, Quinn once discusses his adventures on a talk show, and mentions having met a female version of himself. He is immediately asked, "Did you have sex with her?" (We never really found out if he did, though they did kiss. She was Ax Crazy, anyway.)
 * Doctor Who
 * At the end of the new series' season 4, . Captain Jack, when finding out that "there are three of you now?", says "I can't tell you what I'm thinking right now."
 * And speaking of Captain Jack, it was hinted at in "Utopia" that, as a result of his immortality, he could find a version of himself even at the end of the universe... and then when Jack seems to consider this, followed up with the line that it would be the "only person you'll ever be happy with..."
 * The 2011 Comic Relief special has a timeslipped Amy Pond. If they don't act carefully the slip will stick and they will be stuck with two Amy's, and when asked what he would do then Rory "has a few ideas". Later on, Amy and Amy start flirting with each other.

Amy 2: Yeah. Yeah, you do.

Amy 1: Mmm... I'd give you a driving licence.

Amy 2: I'll bet you would.

The Doctor: Oh, this is how it all ends. Pond, flirting with herself. True love at last. (remembers that Amy's husband is also present) Oh, sorry Rory.

Rory: (nearly catatonic) ... absolutely no problem at all..."

"Ben: So that's what it's like!
 * In "A Good Man Goes to War", the 2011 mid-series finale, River Song strongly implied that she once spent a very enjoyable birthday with two different versions of the Doctor. Lucky girl!
 * Stargate SG-1: Given how much puppetmaster Ba'al was hitting on Adria, what he might have had in plan after one of his clones possessed her may have fit the trope. However, he never got to carry on his plans, so we may never know... which is probably best.
 * Star Trek Deep Space Nine
 * Kira's Evil Counterpart in the Mirror Universe had the hots for her. (Though granted Kira's Evil Counterpart has the hots for everyone.)
 * "Facets" reveals that Curzon fell in love with Jadzia when he was mentoring her; they end up joined to the same symbiote, becoming a retroactive version of this trope by way of The Nth Doctor.
 * On Star Trek TOS, we have the Ho Yay between Kirk and Id!Kirk from "The Enemy Within".
 * Mystery Science Theater 3000 references this trope a couple of times, once when talking about a Time Travel movie (Time Chasers), and once where a character is in a computer simulation with a copy of himself (Overdrawn at the Memory Bank).
 * Rob Brydon's onscreen kiss with Ben Miller on QI after an episode's worth of jokes that they were identical.

Rob: Now I know why my wife married me!"

"Robin: That chick knows what I like."
 * Though nothing comes of it, The Sarah Connor Chronicles has some terribly disturbing one-sided Les Yay from Cameron toward Allison.
 * Robin from How I Met Your Mother honors this trope as well. Once she gets back from Argentina, she undergoes an identity crisis while talking a lot, in her dreams, to her vacation double. When Robin is finally herself again, she mentions that "vacation Robin" popped up in her dreams again and they went all the way.

"Michael: You didn't have to walk out on him like that in front of everyone, you know.
 * On That 70s Show, an episode revolves around Fez having a dream where Kelso gives him a sponge bath. At the end of the episode, Kelso has the same dream (himself giving himself a spongebath). And likes it.
 * Tony has sex with Beth in his series 2 episode of Skins. Possibly. Beth is either a figment of his imagination, an aspect of his personality (his long-lost anima), his sister, himself, a completely random person, or -- most likely -- all of the above.
 * Thirty Rock
 * The incredibly self-absorbed Jenna starts dating a celebrity female impersonator of herself. It's about as close to this as a heterosexual woman can get without the benefits of advanced technology.
 * In the episode where Tracy buys a "Japanese Sex Doll" of himself, Jack asks him why he would make such a purchase "other than the natural inclination to make to love to yourself".
 * During the 100th episode, while everyone is hallucinating, Jack is visited by three versions of himself from his past, an alternate present, and his current future. After he resolves his existential crisis, the three of them stand around and decide that the only rational option is to go have sex with each other.
 * In one episode Hannah Montana, after seeing a picture of herself as Hannah Montana photoshoped to make her look like a guy, Miley comments that she would totally date herself.
 * In the Queer as Folk second season finale, Brian fucks the actor who played a superhero based heavily on himself. This is the catalyst for Justin leaving him.

Justin: I would've told him to go fuck himself, but he was already doing that, in the back room with Rage."


 * An episode of Nip Tuck features a wealthy older gay man who hires the plastic surgeon protagonists to reconstruct the face of his young boyfriend to resemble a younger version of himself.
 * Misfits
 * At the beginning of the third series premiere, new character Rudy mentions that he would definitely have sex with himself if he could. Bravado maybe, but thanks to his power he actually can.
 * The Colbert Report has two Santa Clauses come on stage and make out with each other.
 * The Colbert Report has two Santa Clauses come on stage and make out with each other.

Music
"''Yes, I seduced myself
 * Mindless Self Indulgence expresses a wish for this in "Make Me Cum".
 * "Hot Sauce and Ice Cream", by Tom Smith, features this briefly near the end, before it turns into a Twin Threesome Fantasy.
 * "Destiny Street", from the LP of the same name by Richard Hell and the Voidoids. A time-travel fantasy, IIRC. And Richard Hell is smoking hot.

I took me home

I whispered that only I could make

The younger guy feel less alone.''"

"I've always kind of been partial to calling myself up on the phone and asking myself out. You know... (whoops from the audience) Oh yeah, you call yourself up too, huh? Yeah... Well, one thing about it, you're always around! Yeah, I know. Yeah, you ask yourself out, you know. Some class joint somewhere. The Burrito King or something. You know... Well, I ain't cheap, you know. (...) Well, usually about 2.30 in the morning you've ended up taking advantage of yourself and... there ain't no way around that, you know. Yeah, making the scene with a magazine, there ain't no way around... I'll confess, you know, I'm no different, you know. I'm not weird about it or anything. I don't tie myself up first."
 * Lady Gaga
 * "So Happy I Could Die."
 * Taken to a much more ridiculous extreme in the video for "You And I", where her lover's role in the video was played by herself in her drag alter-ego, Jo Calderone. She also performed the song live as him at the MTV awards.
 * Tom Waits's "Better Off Without a Wife"

""Ich bin alleine doch nicht allein, ich kann mit mir zusammen sein" (I am alone but not alone, I can be together with myself)"
 * Rammstein's "Zwitter"; sung from the perspective of a hermaphrodite who is in love with him/herself.


 * Schaffer the Dark Lord's "Attack of the Clone Fucker".
 * The video for "Sober" by Pink features Pink, in naughty lingerie, making out with... another Pink in other naughty lingerie. Take a look here. Starts about 2:20 and gets intercut here and there nearly to the end.
 * The music video for "The World Is Not Enough" by Garbage has the robot double of the lead singer killing the real singer (Shirley Manson) by kissing her.
 * The video for the Bjork song "All is Full of Love" counts, right?
 * A scene in one version of Janet Jackson's "Together Again" video has Janet Jackson leaning her face and hand on the breast of another Janet Jackson who is wearing a strategically pixelated transparent top.
 * Cat Rapes Dog's song "Adore Myself" is about either this or regular old narcissism.
 * Dave Grohl of Foo Fighters in the video for "Learn to Fly". Twice. A pigtailed girl played by Grohl has a crush on Grohl As Himself, and the Camp Gay flight attendant flirts rather suggestively with the pilot, both also played by Grohl.
 * Nicki Minaj's guest verse in Kanye West's "Monster" has her doing a Split Personality act with her rap, switching between a baby-girl voice and a strident, dancehall-styled 'monster' voice. The video represents this as Monster!Nikki (in black lace and fangs) giving a lapdance to Innocent!Nicki.

Myths & Religion

 * The Bible: This trope goes right back to Adam and Eve, if you believe the whole rib thing. And then there are the interpretations that suggest she was made from a different bone entirely, one present in many mammals but not in humans.
 * Narcissus in Greek Mythology fell in love with his own reflection.

Print Media

 * This Details magazine photo of New York Yankees 3B Alex Rodriguez.
 * The comic strip "Duplicity" that ran in the final issue of Amberzine told the tragic tale of a women who had an affair with a male shadow of herself in Amber universe.

Radio

 * The Arbiter Chronicles: Divergence

Tabletop Games

 * The player's handbook to Aberrant (a White Wolf RPG centered around people developing superpowers as a world-wide phenomenon) contain a chapter with various superhero teams and similar groups across the world (some of which are painfully ethnic). One is the Queer Nova Alliance, an informal group of Novas (superpeople) with "alternate lifestyles". One member is Tommy Orgy, whose selection of powers includes self-cloning. Or, as another nova observes, "Gorgeous, gay, and able to duplicate himself; its a wonder Tommy Orgy ever leaves his house." When Tommy tells another nova to "Go fuck yourself", the other retorts, "I thought that was more your forte, Thomas." A listener adds, "Well, according to every other fanfic I read on the OpNet, anyways..."

Video Games
It's now been revealed that a) the four demo-ready character builds are all different versions of Big Boss, and b) the Love Box is indeed a two-person cardboard box and that if two Big Bosses stay still in it for too long, it will start to jiggle around. Not surprising, as even the guys want Big Boss, and that includes Big Boss. The official website gives an innuendo-filled description of the Love Pack, saying 'in the spirit of camaraderie, some may find it comfortable!'. And also reveals that the characters giggle when taking items from each other, because it tickles. Big Boss is officially the gayest thing in an already incredibly gay series, and for himself. ""Who's that handsome devil?""
 * Metal Gear Solid
 * In Metal Gear Solid 3, dress Snake up to look like Raikov, stand in front of Raikov, and just wait.
 * In the same series, the ridiculous levels of Foe Yay between Solid Snake and his "brother" Liquid Snake.
 * Then there's the marketing campaign for Metal Gear Solid: Peace Walker, which so far seems to be furiously attempting to encourage this as much as possible. The first trailer alone depicted four Big Bosses, and at the end they got in a pink box (labelled "LOVE PACK") which jiggled suggestively, alerting a nearby guard. The second trailer involves soldierly Ho Yay CPR and masculine hand-holding and dialogue about always sticking together, between two Big Bosses. Whether this becomes part of the game or not remains to be seen, but Hideo Kojima is at least having fun with it.
 * Darkstalkers: Morrigan and Lilith are technically two fragments of the same soul. The game art depicts them embracing, naked. What did you expect from Horny Devils? Also, it's not just the game art. In Darkstalkers/Red Earth: Maleficarum is a 2-page picture with Lilith once again embracing Morrigan while looking back at the reader with a knowing grin. (But they're wearing their scanty costumes this time.)
 * In Hell MOO, while you can't actually do this, there are flyers advertising clone services that definitely hint at this, and it is not difficult at all to become an autosexual.
 * Final Fantasy
 * In Final Fantasy VII, Cloud can visit a brothel. In one of the rooms he has one of his frequent psychotic episodes and hallucinates another him, crouched in pain by the hot tub. If you speak to the other Cloud, he berates the real Cloud for being in a place like this, and then leans in to kiss Cloud. The real Cloud passes out as their lips touch.
 * And the Genesis Copies in Crisis Core.
 * Mentioned in the radio and newspaper sources in Grand Theft Auto 4. A scientist has cloned several copies of himself for sexual purposes. And one of his copies is underage.
 * When a Spy dominates an enemy Spy in Team Fortress 2, he will frequently say lines that border on Ho Yay... but it is important to remember that they are essentially the same person.
 * Breeding with Ditto in the Pokémon games may invoke this trope. (We don't know for sure because, if anyone's actually seen the Hot Skitty-On-Wailord Action in person, they aren't admitting it to the protagonists.)
 * In Digital Devil Saga it is almost casually mentioned how Sera was
 * Adding onto the Atlus, Raidou's series have a dimensional rift, allowing Raidou to meet . While they don't stay together all that long (because their meetings always end in ) fanon sometimes persists in shipping the two, mainly played for drama.
 * Played with in Kingdom Hearts 358 Days Over 2. Roxas and Xion become quite close, and Xigbar even gives Roxas dating advice to impress Xion. This quickly turns disturbing when it is revealed It gets even more ridiculous when you learn that Xigbar at some point sees Xion as.
 * Ridiculous is not quite the word I'd use.
 * In Sam and Max Season 2 Episode 1, ghosts of Sam and Max travel to the Christmas of the Future to save their future selves from dying a horrible death on a river of lava. If Sam suggests haunting their future selves, Max says that they should, only if he haunts Future Sam and Sam haunts Future Max -- "otherwise, it'd just be gross". However, he also hits on his future self -- "Hey, sexy! I'll be back to pick you up later!"
 * In Dissidia Final Fantasy, Kefka's Mirror Match battle taunt resembles this trope:


 * Modifying the visuals of certain games, such as Resident Evil, can allow this sort of thing to occur. For example, this video replacing both The Vamp Excella trying to flirt with Big Bad Wesker in series 5 with Chris (although despite the change in appearance the mechanics for the original characters still operate, such as Excella's Jiggle Physics applying to Chris's chest gear).

Visual Novels

 * The eroge X-Change toyed with the idea, having one of the girls apparently resemble Takuya's female form, but with a different hair color.
 * Kichiku Megane
 * This BL Game features uke salesman, Saeki Katsuya, who turns into a super sadistic seme when he puts on a pair of glasses given to him by a mysterious stranger. Several of the game's bonus scenes feature his glasses-wearing seme self doing very naughty things to the normal version.
 * Played to the hilt in the sequel Kichiku Megane R where two of the bonus scenes revolve around Lampshaded when glasses-wearing Katsuya points out that this is only possible because the sequel is also a fandisc.

Web Animation

 * In episode 10 of Retarded Animal Babies, the protagonists travel through the internet, find their creator's Newgrounds profile, and end up entering the beginning of the same episode. Effectively, they have traveled a few minutes into the past and are able to communicate with their past selves. The two Puppies immediately decide to have sex.

Web Comics

 * Xkcd has touched upon this enough for the author to bring up the possibility that it's now "an official xkcd theme". And Here too...
 * Well, it doesn't involve time travel but Black Mage of Eight Bit Theater has an Enemy Without moment, but ends up killing the embodiment of his sins (himself) and re-absorbing all of his evil. Then he decides he needs to do something that makes self-love into an atrocity. Thief then somehow gets pictures and blackmails him.
 * Homestuck
 * Karkat has wondered whether he could be his own kismesis, although in practice that doesn't really work, even considering troll biology. In fact, this seems to be something of a recurring theme with him -- when he sees, he fantasizes about them making out and accidentally mistypes "make myself out to be" as "make out with myself to be" in the connecting log with her.
 * This update reveals that one of Nepeta's many, many ships is Jade auspisticing between past Karkat and future Karkat. Definitely a recurring theme.
 * Space Moose.
 * This strip of Overcompensating.
 * In a Questionable Content filler strip, Tai turns all the men in Northampton into women; Marten now looks exactly like Dora, so, just as planned, they start to make out in front of her.
 * Used in this strip of Saturday Morning Breakfast Cereal.
 * Real Life Comics
 * Subverted in a strip: Greg and Tony travel to an alternate dimension where everyone is gender-flipped. Upon meeting female Greg, Tony comments that female Greg is kinda hot. Greg's reaction to this is not surprising in the least.
 * Played straight later, when it's revealed by female-Greg that male-Liz is dead. Greg cheerfully tells Liz and female-Greg "If you two want to hug, don't stop on my account."
 * Subverted later still, when Greg's female doppleganger offers to swing by and start hanging out with Greg and Liz, Greg replies with: "You freak me out in ways I'm not comfortable dealing with. No offense." Needless to say, female Greg is offended.
 * In a Persona 3 FTW strip on the release date of the PSP version of Persona 3 (which allows you to pick a female main character), both the main character and his female counterpart meet, and well...
 * While Umlaut House 2 only implies a threesome between Saundra, her husband Volair, and his future self... well, it is Volair we're talking about.
 * El Goonish Shive
 * Done with Tedd and Grace go on a date . This is commented on later here by Tedd and then referenced here by Elliot and Sarah with interesting parallels.
 * Panel 3 here has a strong suggestion.
 * Buttersafe, with prokaryotes.
 * In The Adventures of Dr. McNinja, when McNinja's clone is captured, he insists that his father call to make sure that they really have him, and also to "ask him what he's wearing!" Of course, this was Innocent Innuendo that helped the Doctor formulate a plan. That didn't stop his dad from running with the idea and later assuming that he's making out with his clone, because "It's what any of us would do!"
 * A variation in Problem Sleuth: Problem Sleuth and Pickle Inspector's love interests, Hysterical Dame and Nervous Broad, are also mystic Distaff Counterparts created while on a Vision Quest. Luckily for us, Ace Dick's counterpart, Ace Dick In A Bad Wig, is slain before the two can form any sort of romantic attachment.
 * Subnormality made this a punchline to an early strip (later featured on Cracked).
 * Wicked Powered has this as the origin of the main character. Due to a complex sequence of Time Travel, genderbending, and amnesia, he became both of his own parents. And this made him immortal. Oh. And his "aunt" is actually his pet monkey.
 * Touched on in A Softer World. "I would totally make out with my clone. If it was okay with her. No pressure."
 * Erin from Dragon City has admitted to being attracted to an alternate universe version of herself, but her dad pointed out that she might just be narcissistic.
 * Implied in this My Little Pony Friendship Is Magic fan comic, where OC Kidder is nearby a Changeling version of himself and says "Now, neither of us will be vergins! [sic]"
 * When he first gets turned into a woman, after a night of drinking Tiffany of Exiern remarks that she's not as turned on looking at her new body as she thought she would be. Followed by a moment of Brain Bleach at the thought of checking herself out.

Web Original
"Clone #1: What do you want to do?
 * In the Whateley Universe, this is a serious problem to Jobe, as his now-identical clone Belephoebe is also in the body of his ideal girlfriend. And is his daughter, legally. He restrains himself from the urge to make sweet monkey love to her.
 * Invoked, and very nearly practiced, by Doctor What in AH Dot Com the Series "The Narcissus Syndrome" -- with his evil, Mirror Universe, Gender Bender counterpart.
 * Cracked
 * The website ran a column by Dan O'Brien entitled "So You're Locked in a Room with Your Clone: Fight or F#@k?"
 * Cracked also ran a video in which Swaim specualtes about having sex with his own clone. He decides that the morning after would be akward.

Clone #2: I... want to die."

"Brian O'Donovan: You know, I remember reading somewhere that there are only two truly meaningful things you can do with your doppleganger when you're locked in a room. You can fight them... Or f#@k them.
 * And then Agents of Cracked had an episode featuring a Similar Squad, with Dan O'Brien's doppleganger invoking the article written by his counterpart.

(Dan takes a fighting stance)

Brian: Wrong answer."

"Swaim: You slept with your exact duplicate. The clone bone. Sixty-sixing. Dopplegangbang. Mirrorbation. The big auto-erotic enchilada. Twins with benefits."
 * A later episode has Swaim reference this incident, and then provide many potential alternate names for this trope.

""He was fiercely aroused all of a sudden, and he realized that his situation was somewhere in between The Graduate and the lucky guy who gets to take home those blonde beer-ad twins -- no incest taboo, just something more sublime and disturbing. He didn't want to think about it too earnestly, for fear of blowing up the universe.""
 * In the Funny or Die video "Go Fuck Yourself with Dave Franco", the titular Franco goes to a bar, hooks up with himself, and eventually fucks himself. The link is slightly NSFW.
 * Orion's Arm
 * House Stevens is made up of clones who only have sex with those they share their genotype with. This was originally to prevent inbreeding as the 47 original founders were the only humans on their planet and they were all related, so basically incest is okay as long as it's with yourself.
 * Also implied to be happening at the end of Betrayals between Gus and a copy who had been living in a virch for years.
 * In the Global Guardians PBEM Universe, a muckraking tabloid once accused superher Los Hermanos of having done this. While he denied he ever had done so (or even having ever thought about doing so), he also shocked his teammates by admitted that the idea wasn't as repugant to him as they thought it should be as, given that he and his duplicates are a Hive Mind, it would be more akin to masturbation than anything else.
 * Lampshaded in MEL when the eponymous protagonist ends up with not only his love interest but an older version of her from a future where she was embittered by HIS death.


 * It doesn't last however, as the two versions leave him for each other.

""I'd shoot two portals in a vertical line, undo my belt, lean in, and... (Beat)"
 * Rhett and Link have this video about choosing the perfect profile picture. After taking the appropriate steps and multiple shots, "pick the one picture in which you are most physically attracted to yourself".
 * College Humor/Dorkly gives us the following line in Wish I Had a Portal Gun:

Western Animation

 * A sketch on Robot Chicken parodying Best Week Ever, featured Hal Sparks (portrayed as pretty much all people on that show are, as a stop motion action figure) remarking "If anyone ever made a toy of me, I'd have to make out with it". A few seconds later, Hal is shown making out with a considerably less animate but otherwise identical copy of himself. A moment after THAT, he pauses to cheerfully declare to the camera, "It's not gay, it's masturbation!"
 * Futurama
 * It's nowhere near sex, but
 * This is of course the very first thing a nudist alien does after thinking he finds the secret to paradox-free Time Travel in Bender's Big Score.
 * In one of its countless Imagine Spots, The Simpsons had Homer fantasizing what it'd be like to marry himself. Cue the image of a room full of mini-Homers and two adult Homers swapping tongue.
 * Arguably, Warden paired with either himself or his future self is one of the more popular pairings in the Superjail fandom, fueled by a scene in which two versions of himself hug each other at their trial, prompting the judge to tell him to "stop touching yourself!"
 * While Cybertronians are by and large immortal robots who realistically would only have a Purely Aesthetic Gender, Starscream in Transformers Animated seems to come on to his Opposite Sex Clone while asking what she represents in him.
 * A recent episode of Family Guy features Stewie and Brian travelling to other universes, one being where everyone has two heads: One happy, one sad. When we see this universe's Stewie, we see his heads kissing each other. The happy one likes it, while the sad one tries his best to.
 * Aeon Flux has an episode where Aeon is duplicated and, true to her omnisexual nature, makes out with herself, though only briefly... on camera. There was more than one duplicate. And they were all naked, in the same room. Yes, the Big Bad had a cloned harem of his primary nemesis.
 * An episode of American Dad has a future version of Stan offering the Stan from the present a "handy J." According to future Stan, it's not gay, it's "you on you."
 * On Young Justice, Miss Martian demonstrates her shapeshifting powers by turning into female versions of Robin and Kid Flash, leading Kid Flash to wonder, "Is it wrong that I think I'm hot?"
 * Mary Shelley's Frankenhole
 * Ron Howard (and Tom Hanks, but only incidentally) was so narcisistic that he forced hookers to wear mirrors on their faces. Eventually, that wasn't enough for him, so he wanted Frankenstein to make a clone of him. He agreed, but Ron felt it was taking too long and started jumping back through time to have sex with younger versions of himself. This ultimately collapsed the timeline and resulted in a universe populated by an infinite number of Ron Howards.
 * Also with the Were-Lawrence. He finally finds a woman who loves him. Only, having bitten her, she turns into his human form whenever sexually aroused.
 * In the episode "Johnny Alternative", it's strongly implied that Johnny Test falls in love with a female version of himself.

Real Life
""Of course I romance myself. I’ve always said, if I had to make out with my clone, I would.""
 * Not counting masturbation, the closest anyone has come is autofellatio, and while it works for only a few especially limber/endowed guys it's not exactly a comfortable position or easy to breathe in while doing so.
 * There are examples of human men with semi-prehensile penes...if you look, you can find pictures that show men bending their penes in such a way as to allow anal penetration. This makes this trope (sort of) Truth in Television . NSFW...search "self-fuck" on google and you can find video proof of this.
 * The latter example ties into an old joke, where a boy keeps asking his grandfather for items he shouldn't have until he's older (beer, cigarettes, etc.), and is then asked "Can your dick touch your asshole?", the answer always being no. The boy takes out some cookies, grandfather asks for some, boy asks the same question. "Yes, it can." "Well then go fuck yourself, gramma made these cookies for me!"
 * Also, in the same vein, there is autocunnilingus. Though it would be far more difficult, bordering on impossible by some claims, a quick search of the term in the open waters of Google will net you plenty of (probably fake) videos, artwork and edited images -- however, nobody so far has come forth with authentic video proof of the act.
 * This could hypothetically be possible without physical cloning or time travel in a universe the size of a googolplex -- as this video explains, a googolplex is 10 to the power of 10 to the power of 100, or 10 to the power of a googol; however, the number of quantum states that a given area could be in is only 10 to the 10 to the 70. Still a ridiculously massive area, if translated into metres, but if a person were to travel that distance, one could naturally expect to find exact copies of themselves through sheer repetition of their specific quantum state.
 * Too bad our universe isn't even a googol in size. Or, you know, that we don't have space travel anywhere near that fast yet.
 * Felicia Day while talking about a character that she created, played, and wrote the script for in Dragon Age Redemption, says this while interacting with the Ink Suit Actor version of said character in Dragon Age II Downloadable Content:


 * Kevin Smith once did a special for The Tonight Show where he showed some locations in New Jersey connected to his films. At one point he stands next to a replica of himself, and then proceeds to make out with it, saying it's something he always wanted to do.
 * Some have pointed out that Mick Jagger had an awful lot of paramours (and even one wife) who looked like female versions of him.
 * Self pollination in plants -- peanuts, soybeans and a few others.
 * Banana Slugs and other gastropods. They have both male and female sexual organs. If a partner isn't available, they self-fertilize themselves.
