If asked to imagine what prehistoric human sex was like, according to psychologist Christopher Ryan, most of us would conjure "the hackneyed image of the caveman, dragging a dazed woman by her hair with one hand, a club in the other..." Ryan says this image is mistaken in every detail. A much more likely picture of how it went down in prehistoric times was this: a caveman would quietly sit in the corner and watch another caveman have sex with a woman, patiently waiting his turn.
Apparently, prehistoric women were extraordinarily promiscuous, and like our primate ancestors, women are hard-wired to behave like chimps in the bedroom. In his book, Sex at Dawn: The Prehistoric Origin of Modern Sexuality, Ryan offers a biological explanation for why we find monogamy so difficult today. A male is interested in sex with one woman up until the point of orgasm, at which point he will immediately lose interest, fall asleep, or perhaps wonder off to find more action.
In other words, human males are in important ways sexually incompatible with human females, who are capable of multiple orgasms. So what is the evolutionary advantage of this? Take monogamy out of the equation, and the evolutionary logic becomes more evident. A woman can have multiple sexual partners. This may increase her chances of reproducing, and she needs to try it a lot to be successful. Compared to other animals, humans have an incredibly low rate of conception, based on the number of sexual acts we partake in. And so it is well that sex is so much fun for humans, because if that were not the case, we wouldn't have made it this far.
So just what does it mean to make love like a caveman? It means have a lot of sex, partaking in, as Ryan describes it, the "seven million years of primate promiscuity" that our ancestors so heartily embraced as a species. That's a lot of sex.
