A kink is defined as a sexual activity that falls outside of sex that society traditionally considers acceptable That can include everything from role-playing to bondage to whips.
Example of kinky things. Renye adds that people often have more than one kink or one fetish and there is often overlap. BDSM is kinky but not all kinks fall under the BDSM umbrella. Any form of verbal degradation and humiliation can be extremely kinky if lets make that a big IF you both take pleasure in this kind of play.
Always discuss and respect boundaries first.
