If you were a kid or teenager in the 1980s, you may remember the saying “No duh.” This phrase—and the similar, but slightly more edgy, “no doy”—was said to convey that something was obvious or went without saying. For example:
1980s Me: Pizza is really good.
1980s You: No duh!
Why do I bring this up? Because often, “no duh” seems the only appropriate response to certain scientific studies. You know the kind I’m talking about—the ones that report things like “Women are more likely to feel insecure about their bodies after looking at swimsuit models for an hour” (no duh) or “Couples are more likely to stay together when they share common values” (no doy).
So here’s the latest: A recent study found women are more likely to experience simultaneous orgasm with their partner when said partner is hot.
Why is timing of female orgasm important? Well, evolutionarily speaking, a woman’s orgasms served the purpose of increasing fertility by increasing her ability to retain sperm. Yep. But in order for that to work out, the woman has to orgasm within one minute before and 45 minutes after the man does.
What I am taking from this study is that to avoid pregnancy, you should have sex with ugly men (hey, can we see a picture of the male researchers involved here?).
For real, though—there may be a little more than ‘no duh’ going on here. The study, published in Evolution and Human Behavior, looked at the timing and frequency of female orgasms (when engaged in sexual liaisons with a male partner) and found that, on average, women have orgasms before men, and most frequently due to some activity other than intercourse. But when the man involved was very masculine/dominant, his lady was significantly prone to get off more frequently, and either at the same time or just after he did.
Attractiveness, however, only corresponded to timing or female orgasm, not frequency—women paired with men rated high in hotness but not necessarily masculinity/dominance were likely to cum simultaneously with their lovers, but not necessarily more frequently. And neither attractiveness nor masculinity mattered when it came to “orgasms from self-masturbation or from non-coital partnered sexual behavior.”
The researchers say all this supports the hypothesis “that female orgasm evolved to facilitate recruitment of high-quality genes for offspring.”
