Hormones: What I Got You Got to Get It Put it in You

Women wonder "Why the hell are men always so horny?" Men wonder "When the fuck am I finally going to get laid?" We drive each other crazy, don't we? Shannon Elizabeth once said in the January 2000 edition of Maxim magazine that sex is like sugar. The more of it you have, the more you want. She went on to say that she thinks men always have sugar in their system. The "problem" is with men's and women's hormones.

Both sexes have testosterone, but men have ten times as much as women. Testosterone is essential for sex to happen. It makes men aggressive, physically and sexually. Both men and women with the largest amounts of testosterone in their system tend to commit more violent crimes and be more unmanageable in prison. As said before, women also have testosterone but it varies in amount through out the menstrual cycle. Its most common at a specific time: a few days before they ovulate.

Men's testosterone can increase just by being attracted to a woman. It can happen at any time, day or night. So that's why we men are "always ready." We need to be ready for action in case a woman happens to be in the mood. Most of the time, this means we are frustrated by women's seeming lack of interest and women just want us to leave them alone. (It reminds me of an old SNL sketch, where a woman invents a device to cut off her husband's sex drive. She called it "Balls Off" and was a stun gun, applied to his balls.)

Women also have a hormone called estradiol. As a woman's estradiol level increases, so does their desire for sex. It also is most common during ovulation. Researchers found that estradiol, mixed with oxytocin (a hormone released when a person in touched) makes a woman want to have her lover penetrate her. Massages have long been known to be a turn on, and oxytocin is the reason.

Again, all of these hormones are working to the same goal: getting the woman pregnant. Testosterone keeps men constantly willing to have sex. It also makes women want sex, but only when they are fertile. A report in the journal "Human Reproduction" found that sex became more frequent in women's six most fertile days, despite the fact that the women in the study had been either sterilized or were using intrauterine devices. The study suggested that sex doesn't happen at random.

Ironically, oral contraceptives have become part of the experiment. The pill works by blocking androgens (a kind of testosterone), which make a woman horny. In 1978, a study found that women that were on hormonal birth control were less interested and less likely to suggest having sex. Those that were using non-hormonal birth control were more sexually active during ovulation.

This is a simplified way of looking at human sexuality. The above science is just that, science. It doesn't take into account birthdays, alcohol, parties or boredom. All of these things happen outside of a person's hormones.
