Erotic sexual denial is the practice of refraining from sexual experiences in order to increase erotic arousal and/or tension. It is commonly used as sex play within the context of a dominance and submission relationship, though it can also be a solo practice. The prohibited experience can be narrowly or broadly defined and banned for a specific or indeterminate length of time, depending on the practitioner. The experience withheld can be any favored or desired sexual activities, such as specific acts or positions, provided it is something the practitioner wants. Orgasm control practices like edging are well-known varieties of erotic sexual denial in which a person is kept in a heightened state of sexual arousal for an extended length of time without orgasm. Edging often ends with a delayed orgasm, unlike the similar practice of orgasm denial which typically does not lead to orgasm. Chastity devices such as penile chastity cages, cock harnesses or chastity belts can be used as a physical barrier to reduce or deprive an individual of genital stimulation.

In discussions between BDSM partners, negotiation usually focuses on the activities which may or may not be agreed to. 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. Tease and denial Tease and denial is a situation where a person is stimulated until they are close to orgasm, then stimulation is stopped, keeping the person on the brink of orgasm. It is sometimes referred to as "edging". 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
