Cuckolding is a sexual fetish or practice in which a person derives sexual pleasure from watching their partner engage in sexual activity with another person. The term "cuckold" historically referred to a man whose wife was unfaithful, but in the context of the fetish, the cuckolding dynamic is consensual and may involve humiliation, submission, or voyeuristic elements. Cuckolding is based on the exchange of power dynamics and often involves open communication and trust between all parties involved. It is important to note that cuckolding is a consensual sexual activity and should not be confused with infidelity or cheating.
