A professional dominatrix or professional dominant, often referred to within the culture as a "pro-dom(me)", offers services encompassing the range of bondage, discipline, and dominance in exchange for money. The term "dominatrix" is little-used within the non-professional BDSM scene. A non-professional dominant woman is more commonly referred to simply as a "domme", "dominant", or "femdom" (short for female dominance). Professional submissives ("pro-subs"), although far more rare, do exist. A professional submissive consents to their client's dominant behavior within negotiated limits, and often works within a professional dungeon. Most of the people who work as subs normally have tendencies towards such activities, especially when sadomasochism is involved. Males also work as professional "tops" in BDSM, and are called "masters" or "doms". However, it is much rarer to find a male in this profession.
