Dominatrix

Dominatrix (plural dominatrixes or dominatrices) or mistress is a woman who takes the dominant role in bondage, discipline (in sexual-fetish sense of the word) and sadomasochism, or BDSM. A common form of address for a submissive to a dominatrix is "mistress", "ma'am", "domina" or "maîtresse". Note that a dominatrix does not necessarily dominate a male partner; a dominatrix may well have female submissives, nor must the role of a dominatrix involve pain toward the submissive; her domination can be verbal, involving humiliating tasks and servitude.
