Cuckold

A cuckold is a person, usually a man, who derives sexual arousal from their partner being intimate with other people. In BDSM contexts, the term is often associated with humiliation, voyeurism, jealousy play, or dominance and submission dynamics. The expression can vary widely, ranging from fantasy alone to clearly structured roleplay.

It is important to distinguish between consensual arrangements and actual infidelity. A cuckold dynamic only works with clear agreements, boundaries, and the consent of everyone involved. Without consent, it is not a game but a serious breach of trust and consent.
