From Amazon:
In this changing world of what is socially and politically “correct,” polygamy is perhaps the last great taboo. Over the last thousand years, monogamy – at least in name – has been the default setting for coupledom and procreation in the Western world. And yet, throughout history, there have been inklings that “one-man, one-woman” is an uncomfortable institution for human beings. The consistently high rate of marital “cheating” by both sexes, plus the persistent interest in a variety of sexual partners – on the part of women as well as men – suggest strongly that monogamy isn’t easy, and certainly isn’t “natural,” for either sex.
