Cuckolding

Cuckolding is a sexual fetish in which an individual gets turned on by their partner having sexual acts with someone else. This should be not be confused with compersion, which refers to when someone experiences joy associated with seeing one's partner have a sexual or romantic relation with another. It’s closely related to BDSM, including humiliation. The term cuckold usually means a man who was cheated on by his wife without knowing.
