Voyeurism
"Voyeurism" is the sexual fascination with watching others while they are undressed, nude, masturbating or having sex. Voyeurism typically occurs in consensual settings in the adult lifestyle scene, such as swinger clubs, sex-positive clubs, sex clubs, BDSM parties, and private sex events where everyone is aware that they might be watched. While some people alternate between being exhibitionists and voyeurs, many people prefer to observe without taking part. In many nations, it is illegal to watch someone without their knowledge or consent, and it is not regarded as a form of consensual voyeur.
