Lots of people masturbate, although it's not something you'd bring up in polite conversation. However, it's given quite a different treatment in fiction. Unlike NobodyPoops or NoPeriodsPeriod, where the function is simply not mentioned because it would be NauseaFuel, masturbation in fiction often fits into a few different categories:
* It's aimed at or about teenagers (usually PlayedForLaughs) and the character is either a horny teenage boy, or another character, usually the parents, think that he's masturbating when he is very obviously ([[InnocentInnuendo or sometimes not so obviously]]) ''not''.
* The character masturbating is [[HollywoodDateless sexually frustrated]], disturbed, perverted, or is a [[ThisLoserIsYou nerd/has no social life]].
* It's a military or a prison setting (or a single-sex boarding school). The masturbation here would be explained by the shortage of women ([[AmazonBrigade or men]]), boredom and loneliness.
* Artificial insemination due to [[OnlyYouCanRepopulateMyRace lack of partners]], [[AllLesbiansWantKids incompatible sexual orientation]], etc.
* In [[UsefulNotes/{{Pornography}} porn]] or erotica, it can be used for the sexual titillation of the viewers.

Of course, there's a pretty valid reason why "normal" masturbation isn't depicted very often -- it doesn't accomplish much. There aren't many ways that masturbation could advance the plot of a story, and because it's generally a solitary activity, there usually won't be any character interaction involved.

Also note that male masturbation is used far more often than female (except in porn, for the above-mentioned reasons)... though that's not to say that female masturbation isn't given ''any'' attention in fiction (the "Literature/{{Rumpelstiltskin}}" tale supposedly had the [[ValuesDissonance original message]], "women who masturbate become infertile"). In older media, expect references to hairy palms and/or blindness, two widespread myths used to keep boys from masturbating.

!!List of masturbation tropes:

* BreakingInOldHabits - A character receives a replacement hand and immediately uses it to masturbate.
* CaughtWithYourPantsDown - A character is caught masturbating.
* IllBeInMyBunk - A character who steps off-stage is humorously portrayed as leaving to masturbate.
* JizzedInMyPants - Yeah, self explanatory.
* MistakenForMasturbating - Characters think someone who isn't masturbating is.
* PornStash - A character has a personal collection of pornography, and can usually be assumed to use it as an aid to masturbation.
* PoorMansPorn - A character gets off to something not strictly intended to be used for that purpose.
* SelfAbuse - Masturbation is portrayed as bad for you.
