->''Everything is about sex, except sex, which is about power.''
-->-- Creator/OscarWilde (possibly apocryphal)

Tropes related to sex -- or rather, why anyone was ''ever'' born. (Alternatively, given the complex minefield they describe, "How was anyone ''ever'' born?")

Note that these tropes have [[Administrivia/NoRealLifeExamplesPlease all real life examples blocked]], per the Administrivia/ContentPolicy[[note]]Of all the tropes in this category, only 30-something aren't explicitly listed in one of the NRLEP indexes, and all of these (like {{Sexophone}}) are ''not'' about the process itself[[/note]].

For tropes with names that sound sexual but the tropes in themselves aren't, see ItsNotPornItsAnIndex.
