Can't Have Sex Ever/Playing With

Basic Trope: A character can, for some reason over another, never have sex.
 * Straight: Bob is the victim of an ancient curse that will kill him if he ever has sex.
 * Exaggerated: The curse will activate if he ever has sex, gets aroused, or even thinks about sex.
 * Downplayed:
 * Bob's curse will activate if he has sex more than once a day.
 * The ancient curse preventing Bob from having sex is being bald and overweight
 * Justified: Prior to being cursed, Bob was a rapist. The curse was the perfect way to teach him a lesson.
 * Inverted: The curse will activate unless Bob has sex every day.
 * Subverted: Bob has sex and there is no consequence...
 * Double Subverted: ...however, he didn't release, so the technical requirement of the curse wasn't fulfilled.
 * Parodied: Bob is a Catholic priest, but still complains at every opportunity about the curse.
 * Deconstructed: The inability to have sex eventually takes an emotional and mental toll on Bob, as he's not asexual and really misses it.
 * Reconstructed: He finds a way to lift the curse.
 * Zig Zagged:
 * The curse comes and goes; sometimes it is in effect, other times not.
 * The curse only activates if Bob has sex with a woman who's an inch or more shorter than him... on a Tuesday. On Wednesdays, it'll activate if he so much as thinks about having sex, and other days of the week tend to have their own unusual variations.
 * Averted: Bob's life of celibacy is not the result of a curse.
 * Enforced: "We're not allowed to show sex in this work, but we can show a guy who really wants it but can't have it!"
 * Lampshaded: "Well, we're alone in this hotel room with nothing to do..." "Stupid curse..."
 * Invoked: After Bob hurts her feelings, Alice casts the anti-sex curse on him.
 * Defied: "Screw the curse. I need some lovin'."
 * Discussed: "We can't steal that gold from the ancient Egyptian temple. We'll get cursed and then we can't have sex ever or we'll die."
 * Conversed: "Why didn't I pay attention to that movie about anti-sex curses! Now I've been cursed too!"
