– used especially in scenes which may involve consensual force. Scat play: Feces play. Scene: Refers to the setting and participation of a bdsm activity. Sensation play: class of activities meant to impart physical sensations upon a partner, as opposed to mental forms of erotic play such as power exchange or sexual roleplaying. Service submission: A person who enjoys performing a service in a sexual or BDSM environment. Slave: A submissive who consensually gives up total control of one or more aspects of their life to another person (their Master). Soft limits: Something that someone is hesitant to do or is nervous to try. They can sometimes be talked into the activity, but it is preferable if it is negotiated into a scene at a trial stage or at beginner level. Squick: The uncomfortable feeling someone may get when they hear or see certain kinky activities. It can also refer to someone who has no interest in the activity – it "squicks them out" – but who has no prejudice against the play or people who participate.

It is critical that a Dom/top take responsibility for the sub/bottom and be aware of their sub's well-being if they are in subspace. Long-term dominance and submission relationships without impact play may alternatively define subspace as 'a mental state where the submissive feels a deep emotional resonance or connection with the dom'. Switch: Someone who likes being both dominant and submissive, either in one scene or on different occasions. Tit torture: The act of causing deliberate physical pain to the
