Tease and denial

Erotic sexual denial, also known as orgasm denial, is a sexual practice or sex play in which a person is kept in a heightened state of sexual arousal for an extended length of time without orgasm, and is commonly practiced in association with BDSM and sexual bondage. Erotic sexual denial can be another name for or variant of orgasm control.

One form of erotic sexual denial is the reduction or deprivation of all genital stimulation. To ensure a complete absence of genital stimulation, a chastity device may be used as a physical barrier to genital touch or full erection.

Tease and denial is a situation where a person is stimulated until he or she is close to orgasm, then stimulation is stopped, keeping the person on the brink of orgasm. This is similar to orgasm control, but without the promise of orgasm at the end.

If orgasm still occurs after removal of stimulation, it typically brings less pleasure than usual, and is considered a "ruined orgasm", as opposed to being a "denied orgasm" (sometimes known in men as "blue balls"). Alternatively (for men), the release of semen during the emission phase of ejaculation might be prevented by some sort of constriction ("blocked orgasm"). Depending on the relationship, subjects might be repeatedly teased to the point of orgasm several times, but without actual orgasm, causing feelings of intense arousal and psychological need.

To be able to control an orgasm of a partner in such sex games, physical restraints are commonly used. Situations involving bondage are typically called "tie and tease" and can be thought of as extended tease and denial games. This practice is often an integral part of erotic denial. It is notable that in discussions between BDSM partners, negotiation usually focuses on the activities which may or may not be agreed to, rather than the emotions generated by said activities (unless at an unacceptable level). Tie and tease activities are physically as well as psychologically intense, because the strong feelings of sexual frustration are escalated by the sensation of helplessness induced by bondage.
