The sexual game of chastity is usually part of a BDSM fantasy where one partner’s genitals are locked away whilst they are teased and turned on. The anticipation of waiting to be freed allows the wearer to practise self-control, and in the end, have more intense orgasms. This kind of play is also enjoyable for the partner of the wearer who might enjoy the power of teasing and holding the key, meaning the wearers pleasure is in their hands.
