Orgasm denial
Orgasm denial is deliberately keeping someone highly aroused for a long time without letting them climax — building to the brink again and again, then stopping. Closely tied to edging and tease-and-denial, it hands control of a partner's release to someone else, and is a staple of D/s dynamics. Denial can last minutes, a whole scene, or stretch into days and weeks (often alongside chastity). Anyone of any gender or orientation can enjoy it. It overlaps with edging, chastity, and dominance.
For the denied partner, the prolonged, frustrated arousal and surrender of control build craving, focus, and a heady desperation — and make eventual release, if granted, explosive. For the one denying, holding that power over a partner's pleasure is intensely dominant. The longing is the whole point.
One partner is stimulated repeatedly to the edge of orgasm, then stopped just short, over and over — sometimes for a single teasing session, sometimes as an ongoing rule where release must be 'earned' or is locked away with a chastity device. Begging often features.
Physically low-risk, though prolonged intense arousal without release can cause temporary aching ('blue balls' or its equivalent) that's uncomfortable but harmless. Agree on the terms and duration, keep a safeword, and check that frustration stays fun rather than genuinely distressing.
