Fundamentals

BDSM is an umbrella term for certain kinds of erotic behaviour between consenting adults, encompassing various subcultures. Terms for roles vary widely among the subcultures. Top and dominant are widely used for those partner(s) in the relationship or activity who are, respectively, the physically active or controlling participants. Bottom and submissive are widely used for those partner(s) in the relationship or activity who are, respectively, the physically receptive or controlled participants. The interaction between tops and bottoms—where physical or mental control of the bottom is surrendered to the top—is sometimes known as "power exchange", whether in the context of an encounter or a relationship.
