Humans have been debating the definition of “normal” as regards sexuality ever since we climbed dripping wet out of the swamps and looked around in search of intimacy. In between conducting sieges, banging vengefully on each other, and finding other fun ways to be hurtful, our ancestors have loved and lived in a bewildering variety of ways. Look at the ancient Greeks, who practiced homoeroticism openly and with impunity, as their decorated pottery attests. The Romans looked askance at intimate relations between men but it was okay for women to engage in it, I’ve read. They had another hang-up: if women were raped, it humiliated the entire family, especially the male members, and was considered the women’s own fault. (Punish the victim is still a favorite playbook in many Middle Eastern quarters, not to mention closer to home. Sometimes the raped woman is disowned or even killed.) The Egyptian pharaohs reputedly practiced incest, marrying brothers to sisters, or fathers to daughters, to perpetuate the throne within the clan, although some scholars now dispute this in part because incest was frowned on for ordinary folk. The point may be, what was conventional or “normal” depended on where you lived, when you lived, and what your status was on the social ladder.
