As a burgeoning sexuality student I had a mild obsession with the human implications of bonobo sexual behaviors. They were like this unshared secret of zoology, hidden from sight on nature channels because of apparent prurience and I wondered if we could locate some inherent sexual truth about humanity by looking at bonobos. But doing that means locating the same truths in chimpanzee behavior. Human predilection towards rape, war, and infanticide would be just as valid as promiscuity, cooperation and sex for the fun of it.
In evaluating and understanding our own, often confounding, sexual behaviors I think it’s a mistake to hold any other animal up as an ideal or try to identify immutable parts of our sexual behavior by observing them. Continue reading Can We Do It Like Bonobos?→
I stood in front of the bathroom mirror running my hands over the marks he’d left on me. Little nibbles and scratches, like sexual graffiti on my skin. Flashes of his flesh surged through my mind and I smiled as I fantasized about what we could do the next time.
Humans are not prairie voles. We are not guinea pigs or mice. We’re humans.
Pop science loves to trot out research on rodents to confirm or challenge behavioral assumptions. But what the writers often miss is that our behaviors are shaped by far more than food, fights, flights and fucking. Humans are highly complex social primates and, because of this, our responses to the world can be difficult to explain with simple biology or neurotransmitters.
The tired trope of aggressive male sexuality is a pervasive one. The story goes like this: because men are full of testosterone and sperm as well as unhindered by the consequence of pregnancy, their sexuality is naturally brutish and promiscuous. Testosterone fuels aggression, billions of sperm want hundreds of outlets and nature failed to offset these desires with physical dangers associated with reproduction.
The compliment to this heterocentric sex story is that women, with their limited eggs, lack of testosterone and pregnancy burden are naturally chaste and self protective. Any sexual adventurousness or licentiousness is only done to please men and keep them around so they will help with the child rearing.
A recent study about men faking orgasms came out last week and sparked the usual reactions about “faking it”: personal admission, condemnation, and advocating for more communication to battle this scourge.
People love explaining human sexual behavior with evolution. If a behavior exists, it must be because of evolution…right?
In a recent study, among 827 women who self-reported on sexual behavior and fantasies, those women in the 27-45 age range reported the highest frequencies of sex and fantasy. The study authors explain this with evolutionary theory: older women compensate for their aging uterus by being hyper-sexual. Essentially, they’re saying an aging female brain incites more sexual desire in order to compete with younger (and ostensibly more attractive) females.
Here are my critiques of this analysis:
Nulliparity. If the evolutionary explination is correct, you would find that nulliparous women (those that have never borne a child) would have higher rates of sexual fantasy and behavior than women in their age cohort with one or more children. Pregnancy and childbirth are hard on the human body so it makes sense to level off sexual desire with age if a woman has already had children and women with no children would have more of an impetus to be hypersexual. An earlier study by the same researcher found no difference on account of having children or not.
Does not account for fecundity. Women with higher fecundity (fertility) would be less likely to need this adaptation because they get pregnant easily.
Fails to address social factors. The social taboo against female desire for the sake of desire can compel younger women to avoid sex and actively resist fantasies. Factor in roommates, ability to assess or obtain a sexual partner and sexual confidence, and an argument for social conditioning emerges.
Simplifies evolutionary theory to explain one strategy. Multiple mating strategies and behavioral adaptations exist within the same species. I’ve written about oversimplification of evolutionary theory in media before.
No cross-cultural or longitudinal comparisons. If the “cougar” approach to mating is indeed an evolutionary adaptation, you would find this phenomenon in many locales and points in history. I checked into data from the Kinsey Studies and the evidence is a bit muddled concerning frequency. Women reported a gradual rise in solitary sexual practices (ie jillin’off) but the website summary does not state when that behavior begins to level off.
I freely admit my bias when it comes to evolutionary explanations, especially concerning desire. The biggest reason is that the evidence is contrary to my experience as well as many of my female friends. When I was a teen my sexual desires came into conflict with basic social acceptance. I felt horny but I didn’t know what to do. I didn’t even realize that masturbation was an option for me. Instead, I supressed everything I felt between my legs and was constantly frustrated. One time, at 16, I was so horny I actually cried.
And no wonder. If the recent public outrage and ridicule of Taylor Momson’s vibrator comment is any indication, young women are still being shamed about their sexual desire.
I’m not in Time’s “old lady” category just yet (27-45, WTF?) but I definitely fantasize more and have more sex. Why? I don’t feel ashamed about it. Simple as that. Cheers to getting older and learning when to not give a fuck about others’ opinions.
Note: I am not saying that biological factors are meaningless in this case. Rather, a completely biological explanation is insufficient to explain human sexual desire.
