->''Just erotic, nothing kinky. It's the difference between using a feather and using a chicken.''
-->-- '''Creator/TerryPratchett''', ''[[Literature/{{Discworld}} Eric]]''

A sexual fetish (or, more properly, a paraphilia) is getting turned on by something that isn't considered a normal turn-on by one's culture. Of course this means what is considered a fetish [[ValuesDissonance will vary]], and puritanical cultures will even consider any form of arousal to be taboo. ''Anything'' that isn't a normal turn-on could be a fetish. That is the other reason not to go into a detailed description of what exactly a fetish is. In fiction, there are general clues to show [[AuthorAppeal what's being treated as a fetish]]--namely, how people react to someone being aroused by something. If people are either disgusted or uncomfortable talking about it, it's generally a fetish. If people are impressed, it's kinky, but still on the edge of normal. [[BoundAndGagged Handcuffs]] can easily slide between fetish and kinky this way.

It's still uncommon to see a fetish openly discussed in mainstream fiction, and rare to see those with a fetish ''not'' treated like [[AcceptableTargets weirdos]].

Compare RuleThirtyFour, RuleOfSexy, FetishFuel (when something in media sets off a viewer's fetish, while this trope is when someone ''on the show'' is turned on).
