Dominance and submission (D/s) is a term used to describe the erotic or sexual behavior in which one person gives up their control to another. This is common in the BDSM community. Some individuals use D/s only during sexual role playing, while others may live in a full-time D/s relationship. Although physical dominance is a common element in dominance and submission scenarios, emotional and psychological dominance is also quite common, such as when a dominant orders his or her submissive to perform a sexual act.
In the BDSM community, the word dominant, or any other variation of the word, is capitalized when written.
