Kink. A specific sexual preference or turn-on, often one that most other people don’t have. BDSM involves a number of kinks. Other examples of kink can be a material, like leather, latex or rubber; a given sexual scenario or fantasy, like watching someone else having sex—hopefully with their consent—enjoying threesomes, or being into anime characters. Another word for kink is a fetish. Someone who identifies with being into kinky sex is often called a kinkster or a fetishist.
