A couple months ago, at a group dinner, one non-American gentleman at the table said, "I have had sex with other women, but I have never cheated on my wife of 20 years." This was surprising coming from a man. Usually men consider infidelity the sole physical act; women tend to emphasize emotional betrayal. When I probed the guy on his answer, he just said that Americans are too obsessed with sexual monogamy. "What matters," he said, "is that you still love your partner."
Christopher Ryan and Cacilda Jethá, the authors of the new book "Sex at Dawn: The Prehistoric Origins of Modern Sexuality," would agree. In their fascinating interview on Salon, they explain their ideas, the central one being that monogamy is against our nature. Excerpts, emphases mine:
Marriage in the West isn’t doing very well because it’s in direct confrontation with the evolved reality of our species. What we argue in the book is that the best way to increase marital stability, which in the modern world is an important part of social stability, is to develop a more tolerant and realistic understanding of human sexuality and how human sexuality is being distorted by our modern conception of marriage.
Does this mean that humans didn't form couples before the advent of agriculture?
Because human groups at the time knew each other so well and spent their lives together and were all interrelated and depended upon each other for everything, they really knew each other much better than most of us know our sexual partners today. We don’t argue that people didn’t form very special relationships — you can see this even in chimps and bonobos and other primates, but that bond doesn’t necessarily extend to sexual exclusivity. People have said that we’re arguing against love — but we're just saying that this insistence that love and sex always go together is erroneous.
I think from a cultural standpoint the idea of strict monogamy has far less currency within the gay male world than it does within the straight world. I’m a gay man, and I think probably about half the gay male couples I know are in open relationships. Why do you think that is?
First of all, they’re both men, so they both know what it’s like to be a man. They both know from experience that love and sex are two very different things, and it seems that for women the experience of sexuality is much more embedded in narrative, in emotion, in emotional intimacy…..
I’ve been living off and on for almost 20 years here in Barcelona, and from outside, the United States looks very adolescent, in a positive and negative sense. There's its adolescent energy — its idealism — but there’s also an immaturity and intolerance toward the ambiguity of life and the complexity of relationships. The American sense of relationships and sexuality tends to be very informed by Hollywood: It’s all about the love story. But the love story ends at the wedding and doesn't go into the 40 years that comes after that….the American insistence on mixing love and sex and expecting passion to last forever is leading to great suffering that we think is tragic and unnecessary.
Here's my old post on whether you would still trust someone in the boardroom if you knew s/he was cheating on her/his partner. Here's a dense essay about how lesbians have the least sex of anyone. If all this is too depressing, here's an uplifting video of soldiers returning home and surprising their families.
