Sadist

In the BDSM (bondage, dominance, masochism, sadomasochism) community, the consensual use of sadomasochistic practices is common. For submissives, allowing someone else to control their sexual pleasure can be a turn on, while some measure of pain is said to heighten sensation, excitement, and therefore, sexual arousal. For the dominant in the situation, being in control of another's person pleasure - and to some extent their bodies and minds - is also a stimulating part of the game. In BDSM, the consent and comfort of both partners tends to be valued, and play often starts with the establishments of limits and safe words to ensure both participants' safety and integrity.
