Bondage and Domination (B&D) is an alternative relationship in which a Master or Dom controls the actions, emotions, and will of the slave, or submissive, often referred to as sub. B&D does not necessarily refer to the sex act itself. B&D is more akin to a seduction. The Master seduces the slave with his power, the slave seduces the Master with their willingness and servitude. Sex does occur in the relationship, but in this Guide, we are discussing the lifestyle, not sexual practice.
