Cuckold historically referred to a man with an adulterous wife. It has largely fallen out of use in modern English with the decline of marital infidelity in pop culture literature. In modern English it generally refers to the sexual fetish of the same name in which a male gains sexual gratification from his partner's having sex with other males.[1]
In Western traditions, cuckolds have sometimes been described as "wearing the horns of a cuckold" or just "wearing the horns"
