Both male and female have the same urge for sex.Differentiation in terms of their overt behavior is due sociological constraints.Basic instinct remains the same.However the approach to sex overtly is conditioned by the male instinct of ‘Protection’ towards the female counterpart makes it imperative for the male to be overtly aggressive in terms of sexual advances and behavior.
Shorn of all civilizational clothing and hypocrisy(these too have a place in the emotional well-being of human beings), we are animals first.
Hence Nature has endowed us the urge to have sex with the sole intention of propagating the species and sexual enjoyment is a spin-off and not an end in itself.
Hence classification of behavior into male and female is only academic and we need not go to the extent of assuming theories ourselves and try to prove the same.
Nature is what is.Our dissection of the same is irrelevant to it.
Sexual urge is reinforced, nay, arises, because of emotional content.No sex is possible without emotional content.
Sexual behavior is determined by genes,ethnicity,mores,customs, civilizations and culture.
Men who cheat on their spouses have always enjoyed an expedient explanation: Evolution made me do it. Many articles (here is one, and here is another), especially in recent years, have explored the theory that men sleep around because evolution has programmed them to seek fertile (and, conveniently, younger) wombs.
(See the top 10 political sex scandals.)
But what about women? If it’s really true that evolution can cause a man to risk his marriage, what effect does it have on women’s sexuality?
A new journal article suggests that evolutionary forces also push women to be more sexual, although in some unexpected ways. University of Texas psychologist David Buss wrote the article, which appears in the July issue of Personality and Individual Differences, with the help of three grad students, Judith Easton (who is listed as lead author), Jaime Confer and Cari Goetz. Buss, Easton and their colleagues found that women in their 30s and early 40s are significantly more sexual than younger women. Women ages 27 through 45 report not only having more sexual fantasies (and more intense sexual fantasies) than women ages 18 through 26; the older women also report having more sex, period. And they are more willing than younger women to have casual sex, even one-night stands. In other words, despite the girls-gone-wild image of promiscuous college women, it is women in their middle years who are America’s most sexually industrious.
By contrast, men’s sexual interest and output, usually measured by reported number of orgasms per week, peaks in the teen years and then settles to a steady level (an average of three orgasms per week) for most of their lives. As I pointed out in March, most men remain sexually active into their 70s. According to the new study, as well as the one I wrote about in March, women’s sexual ardor declines precipitously after menopause.
Why would women be more sexually active in their middle years than in their teens and 20s? Buss and his students say evolution has encouraged women to be more sexually active as their fertility begins to decline and as menopause approaches.
Here’s how their theory works:
Our female ancestors would have grown accustomed to watching many of their children — perhaps as many as half — die of various diseases, starvation, warfare and so on before being able to have kids of their own. This trauma left a psychological imprint to bear as many children as possible. Becoming pregnant is much easier for women and girls in their teens and early 20s — so much easier that they need not spend much time having sex.
(Read abut cougar cruises.)
However, after the mid-20s, the lizard-brain impulse to have more kids faces a stark reality: it’s harder and harder to get pregnant as a woman’s remaining eggs age. And so women in their middle years respond by seeking more and more sex.
To test this theory, Buss and his students asked 827 women to complete questionnaires about their sexual habits. And, indeed, they found that women who had passed their peak fertility years but not quite reached menopause were the most sexually active. This age group — 27 through 45 — reported having significantly more sex than the two other age groups in the study, 18 through 26 and 46 and up. Women in their middle years were also more likely than the younger women to fantasize about someone other than their current partner. The new findings are consistent with those of an earlier Buss paper, from 2002, which found that women in their early 30s feel more lustful and report less abstinence than women in other age groups. In both studies, these findings held true for both partnered and single women, meaning that married women in their 30s and early 40s tend to have more sex than married women in their early 20s; ditto for single women. Also, whether the women were mothers didn’t matter. Only age had a strong affect on women’s reported sexual interest and behavior.
And yet there are a few flaws with the data in the new paper. Chiefly: some three-quarters of the participants in the study were recruited on craigslist.com, a website where many go to seek hook-ups, meaning there’s a self-selection problem with the sample. (The other participants were students at the University of Texas in Austin.) The authors also note that there are some alternative explanations for why women in their 30s and early 40s might be more sexual. Many of them may simply be more comfortable with sex than women in their teens and early 20s. Still, that raises the question of why they are more comfortable: perhaps evolution programmed that comfort.
Buss is the author of the groundbreaking book The Evolution of Desire: Strategies of Human Mating, which is now in its fourth edition, and he has become strongly associated with evolutionary explanations for sexual behavior. His theories explain why men can be cads — and, it turns out, why women can be cougars.
