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.
