Exploring the evolutionary origins of modern sexuality.

What If Tiger Were a Tigress? (Female Libido, Part I)

Why are women so noisy in bed?

Several readers have requested more discussion of female sexuality, in terms of the extra-curricular activities we've seen famous men getting up to recently. So, ever responsive to readers' wishes, the next few posts will concern the mysteries of the human female's libido...

 

"Now there you have a sample of man’s 'reasoning powers,' as he calls them. He observes certain facts. For instance, that in all his life he never sees the day that he can satisfy one woman; also, that no woman ever sees the day that she can’t overwork, and defeat, and put out of commission any ten masculine plants that can be put to bed to her. He puts those strikingly suggestive and luminous facts together, and from them draws this astonishing conclusion: The Creator intended the woman to be restricted to one man."

Mark Twain, Letters from the Earth

 

Here’s a question we ask the audience every time we give a public presentation: If you’ve ever heard a heterosexual couple having sex (and who hasn’t?), which partner was louder? The answer we get every time, every place—from men, women, straight, gay, American, French, Japanese, and Brazilians—is always the same. Hands down. No question about it. Not even close. We don’t have to tell you because you already know, don’t you? Yes, the “meek,” “demure,” “coy” sex is the source of the high-decibel moaning, groaning, and calling out to the good Lord above, neighbors be damned.

But why? Within the framework of the standard narrative of human sexuality, what scientists call female copulatory vocalization (FCV) is a major conundrum. Evolutionary psychologists like Steven Pinker like to claim that “[i]n all societies, sex is at least somewhat ‘dirty.’ It is conducted in private….” Then why would the female of such a species risk attracting all that attention?  Why is it that from the Lower East Side to the upper reaches of the Amazon, women are far more likely than men to loudly announce their sexual pleasure for all to hear?

And why is the sound of a woman having an orgasm so difficult for heterosexual men to ignore? They say women can hear a baby crying from a great distance, but gentlemen, we ask you, is there any sound easier to pick out of the cacophony of an apartment block—and harder to ignore—than that of a woman lost in passion?If you’re one of the ten or fifteen people alive who have never seen Meg Ryan’s fake orgasm scene in "When Harry Met Sally," go watch it now (here's a link). It’s one of the best-known scenes in all of modern cinema, but if the roles were reversed, the scene wouldn’t be funny—it wouldn’t even make sense.

Imagine: Billy Crystal sits at the restaurant table, he starts breathing harder, maybe his eyes bug out a bit, he grunts a few times, takes a few bites of his sandwich, and falls asleep. No big laughs. Nobody in the deli even notices. If male orgasm is a muffled crash of cymbals, female orgasm is full-on opera. Full of screaming, shouting, singing, people standing around with spears, and table pounding sure to quiet even the noisiest New York deli.

Female cries of ecstasy aren’t a modern phenomenon. The Kama Sutra contains ancient advice on female copulatory vocalization in terms of erotic technique, categorizing an aviary of ecstatic expression a woman might choose from: “As a major part of moaning, she may use, according to her imagination, the cries of the dove, cuckoo, green pigeon, parrot, bee, nightingale, goose, duck and partridge.”

But apart from barnyard erotic technique, it just doesn’t make sense for the female of a monogamous (or “mildly polygynous”) species to call attention to herself when mating. On the other hand, if thousands of generations of multiple mating are built into modern human sexuality, it’s pretty clear what all the shouting’s about.
