Why We Become Sex Crazed At Age 27

Reaching our mid-30s can be fabulous. That's something we learned from watching our girls in Sex and The City.

Except, when our birthday finally dawns on us, and we start to look at our future... and think about how quickly this age crept up on us... and how quickly the next year will, too. And, honestly, for many women, aging woes seem to be less about wrinkles or becoming a cougar or no longer being asked for ID. What often crowds our minds are our biological clocks. By 30 and continuing into our 40s, all we can hear is a faint, imaginary murmur from our anxious tubes: tick-tock, tick-tock. It's this "sound" that, according to new research from the University of Texas-Austin, that drives us to "capitalize on our remaining childbearing years." 30-Something Women Have Babies On The Brain

In layman's terms, we have sex and lots of it.

And although there is a little Samantha Jones in all of us (maybe a lot for some of us), the study attributes "adventurous bedroom behavior" not to our upbringing or racy TV shows but to low fertility. The study, published in the July edition of Personality and Individual, found women between 27-45 (those in the "low fertility" category) to possess a "heightened sex drive in response to their dwindling fertility," and that these women are "more likely to have frequent sexual fantasies, an active sex life, and a willingness to have casual sex."

"Our findings suggest that women don't necessarily go 'baby crazy' in their 30s or go around thinking they're supposed to be having a 'sexual peak,'" Judith Easton, one psychologist said. "Our results suggest there is nothing special about the 30s, but that instead these behaviors manifest in all women with declining fertility."

So our desire to have sex, at least past age 27, is driven more by nature and less by nurture, it seems. Isn't it nice to have science remind us of our animal nature just when technology, modern medicine and all our civilized human rituals let us nearly forget where we came from? Kind of?

One last and final note: we were shocked to know our fertility starts declining as early as age 27. Can't nurture have a little talk with nature to get our biological and sociological clocks in sync?

Readers, how do you feel about this study? Do you worry about your biological clock?
