Female dominance (or Femdom) refers to BDSM activities where the dominant partner is female; the submissive partner may be of either sex. It can also refer to non BDSM based relationships, that are based on P.E (power exchange) and D/s (Dominance and submission), where the general overall relationship dynamic is female led, and the female dominance is not solely, or only partly defined on BDSM interests. Female dominant relationships may or may not include BDSM activities.
