June 1, pm Updated June 1, pm. Not for so-called Stags, though. These guys get their rocks off watching their wife or girlfriend having sex with other dudes. The Stag either joins in or watches as a voyeur. However you could be mistaken for thinking that as the definition of a cuckold is a man who enjoys the act of his wife being pleasured by another male. The Bull, the wife or both dominate the encounter and the cuckold gets his sexual thrill from the masochistic shame and humiliation.
