Erotic sexual denial, also known as orgasm denial, is a sexual practice in which a person is kept in a heightened state of sexual arousal for an extended length of time, without being allowed to orgasm, and is commonly practiced in association with BDSM and sexual bondage. Erotic sexual denial is a more extreme form of orgasm control, in which the subject is ultimately allowed to climax.

An alternative form of erotic sexual denial is the total denial of all genital stimulation. To ensure a total denial of stimulation, a couple may use a chastity device that physically prevents touch to the genitals and/or full erection.
