Cuckoldry refers to a situation where a man is unaware that his partner is being unfaithful, particularly in a sexual context. Traditionally, the term has been used to describe a husband whose wife has been unfaithful, often without his knowledge. The concept has historical roots and has appeared in literature and folklore throughout the ages. In modern contexts, cuckoldry can also refer to consensual non-monogamy, where a partner is aware of and accepts their significant other's sexual relationships with others. This practice can involve various dynamics and is sometimes explored in BDSM communities, where it may include elements of humiliation or power exchange.
