. "A dominatrix (plural dominatrixes or dominatrices) or mistress is a woman who takes the dominant role in bondage, discipline (in the sexual-fetish sense of the word) and sadomasochism, or BDSM.A dominatrix might be heterosexual, homosexual, or bisexual; but her orientation does not necessarily limit the genders of her submissive partners. The role of a dominatrix may not even involve physical pain toward the submissive; her domination can be verbal, involving humiliating tasks, or servitude."@en .
