If fictional characters knew that being good gets you good sex, there might not be any villains. One common way this shows up, especially in Comedy, is with Sexual Karma. Though not just in the sense of "you give good sex, you get good sex back" (which can certainly come into play, but is not the end of it). What happens is that good characters will, through wacky and unpredictable happenstance, usually end up falling into a veritable harem of highly desirable and willing members of their preferred gender, while the Jerkass will be dumped into a veritable harem of their least favored members of their (un)preferred gender. While in chains. Where no one can hear them scream.
