What is a Cuckold?
The word “cuckold” comes from the mating rituals of the cuckoo bird. The female cuckoo procreates with an alpha-male. He then goes on to impregnate other females cuckoos. The impregnated female returns to her beta-male mate, and they nurture and raise the baby birds born of her “one night stand.” The dictionary definition of a cuckold is “a man with an unfaithful wife.” 
Historically, if a woman cuckolded her husband publicly he became the object of scorn and ridicule. She was the adulterer and he was her cuckold. For the purposes of this essay, a cuckold is defined as being sexually aroused by his wife’s infidelity, so much so that he encourages, supports and engages in his wife taking other lovers.
