Prudes shouldn’t go into archeology. The patina of antiquity may make a carved ivory phallus, Venus figurine, or vulva painting on a cave wall priceless, communicating to us from a mute, distant past. But transplant those images to the modern world and you get dildos, Playboy, and Georgia O’Keefe. Still, most prehistoric erotic art is abstract, disembodied. It doesn’t explicitly depict sex-crazed ancients screwing their brains out for fun and fertility.
