Scarlett's shacking up with Ryan Reynolds. Ashlee is with Pete Wentz. And Lindsay has reportedly gone lesbian. Must be springtime! And in honor of the season, the New York Times has come out with a special look at sex & love (well, mostly sex!) in its Tuesday Science section. We stripped down, got into bed with the 22-incher, and went to work. After the jump, six things we learned about sex, not including the existence of something called the Rigiscan, a device that measures "male tumescence". Hope they clean that off between tests!

1. Men are pretty much born with their sexual preference already determined. In fact, male homosexuality may be imprinted on a developing fetus by some sort of "maternal immune response" to multiple male pregnancies. (It's always mom's fault, isn't it?) In addition, women are total turn-on sluts!

Whether women describe themselves as straight or lesbian, "Their sexual arousal seems to be relatively indiscriminate — they get aroused by both male and female images," Dr. Bailey said. "I'm not even sure females have a sexual orientation. But they have sexual preferences. Women are very picky, and most choose to have sex with men."

2. Young people nowadays are more sexually active and not as moralistic as they used to be, but they still haven't been given proper sex education in high school.

3. Women are pickier than men when it comes to dating: They're less likely to date someone of another race, or a man who is shorter than them (unless, of course, he's loaded!) Also, Op-Ed columnist John Tierney knows a man who can't stand women with dirty elbows.

4. Scientists now believe sexual response starts in the body before it becomes conscious to the mind, often in response to subconscious stimuli. Men who are uninhibited about their sexuality are more likely to be turned on by images of sexual brutality. Many women use sex to raise their spirits. Oh, and again, women are total turn-on sluts!

Women's genitals, it seems, respond to all sex, all the time. Show a woman scenes of a man and a woman having sex, or two women having sex, or two men, or even two bonobos, Dr. Chivers said, and as a rule her genitals will become measurably congested and lubricated, although in many cases she may not be aware of the response.

Ask her what she thinks of the material viewed, however, and she will firmly declare that she like this scene, found that one repellent, and, frankly, the chimpanzee bit didn't do it for her at all.

5. A synthetic hormone developed to help prevent skin cancer by darkening pigmentation of the skin may be our best hope for a female Viagra. Tanned and horny? We can all be Paris Hilton!

6. Lastly, getting old is not a death-sentence for your sex life. Elderly people are even getting it on in nursing homes!
