Death by Sex/Playing With

Basic Trope: Having sex = death of characters
 * Played Straight: Alice and Bob have sex, and one or both die soon after, whether of STDs or something else.
 * Exaggerated:
 * Alice and Bob have sex, and one or both die during the sex act.
 * If Alice or Bob so much as think about sex, they will die.
 * Downplayed: Varies depending on what base you're in, like getting a bruise after a kiss to the lips or being in critical condition after a night of mutual masturbation.
 * Justified:
 * Alice or Bob have an STD that can be fatal.
 * Alice and Bob were so distracted by the sex they didn't see the slasher coming.
 * Alice and Bob are teenagers who Can't Get Away with Nuthin'.
 * Alice and Bob are Starfish Aliens who are genetically programmed to die shortly after mating and laying eggs.
 * Either one is a disturbed Vigilante Man using... unusual methods to entrap rapists, perverts and other sexual scum, which the other is.
 * Bob is a male spider.
 * Inverted:
 * Alice and Bob are zombies who must have sex in order to come back to life.
 * Alternatively: Alice and Bob will die of UST if they do not have sex.
 * The slasher kills all the virgins, but the sexually active Battle Couple defeat him.
 * Subverted:
 * Alice and Bob have sex, but neither dies as a result.
 * Alice and Bob wait to have sex so their first time will be special, but one or both dies before the act is consummated.
 * Double Subverted: However, they do die during the series or movie.
 * Deconstructed: Alice and Bob decided to take the plunge on very uneven ground in the relationship. They can't really enjoy it because of their standing with each other. They die in very poor conditions, they are also reveled to have been in the act, making many people mad.
 * Reconstructed: After finding each other and coming into the arena of love near an end in the timer on their life, such as disease or some curse being put on them, Alice and Bob decided to go out in the best physical event possible. During that time they both enjoy it for all it's worth, not being held back by anything or anyone, allowing them to go out in the best way possible.
 * Parodied:
 * The slasher comes up and sees Alice and Bob in an act of Auto Erotica, rolls his eyes, and blatantly stands there waiting for them to finish.
 * The slasher walks the Earth, and only goes after couples having sex. ONLY when they're having sex. He backs off during false alarms.
 * Alice and Bob die from having G-Rated Sex.
 * Lampshaded: "Did you just dare to have sex? YOU WHORE!!! DIE!!!"
 * Averted:
 * Alice and Bob do not die as a result of having sex.
 * Alice and Bob do not have sex.
 * Enforced:
 * Alice and Bob are teenagers who Can't Get Away with Nuthin' for the sake of a Very Special Episode in a Teen Drama meant to Scare'Em Straight.
 * An abstinence-only sex-ed class meant to Scare'Em Straight.
 * A Slasher Movie relying on some old cliches.
 * Invoked:
 * Alice's Overprotective Dad finds out about Bob screwing his daughter and heads over to Bob's house with his weapon of choice.
 * Alice and Bob are Mauve Shirts preparing to make a More Hero Than Thou Heroic Sacrifice who decide that You Don't Want to Die a Virgin, Do You?
 * Alice and Bob have sex specifically in order to lure the killer into a trap.
 * Defied: The slasher sees Alice and Bob in an act of Auto Erotica, rolls his eyes, and goes off to slash someone else.
 * Played For Laughs: See "parodied"
 * Played For Drama: Almost always is.
