Why is some gay

More information
Category: Ireland‎
While female sexuality appears to be more fluid, research suggests that male gayness is an inborn, unalterable, strongly genetically influenced trait. But considering that the trait discourages the type of sex that leads to procreation — that is, sex with women — and would therefore seem to thwart its own chances of being genetically passed on to the next generation, why are there gay men at all? This longstanding question is finally being answered by new and ongoing research. For several years, studies led by Andrea Camperio Ciani at the University of Padova in Italy and others have found that mothers and maternal aunts of gay men tend to have significantly more offspring than the maternal relatives of straight men. The results show strong support for the "balancing selection hypothesis," which is fast becoming the accepted theory of the genetic basis of male homosexuality.

Ask a Homo: Why do some lesbians dress like men?

Between 2 and 11 percent of human adults report experiencing some homosexual feelings, though the figure varies widely depending on the survey. Homosexuality exists across cultures and even throughout the animal kingdom, as the authors of a mammoth new review paper on homosexuality write. Between 6 and 10 percent of rams prefer to mount other rams, not ewes. Certain groups of female Japanese monkeys prefer the company of other females:. In certain populations, female Japanese macaques will sometimes choose other females as sexual partners despite the presence of sexually motivated male mates. Female Japanese macaques will even compete intersexually with males for exclusive access to female sexual partners.

Why Some Gay Men Hate Pride Parades — And Ourselves

Straight women are much more likely to get themselves knocked up than gay women. So, in terms of evolution, they would seem to have a better chance of passing on their genes, while at the same time it would seem that the genes that make women gay would quickly vanish from the gene pool. This raises the question, why are there gay women? Lesbianism is indeed at least 25 percent genetic, as determined by a study of twins conducted in the United Kingdom. The study found that identical twin sisters who share percent of their DNA are more likely to both be lesbians than are fraternal twin sisters who share just 50 percent , proving that, all other environmental factors being equal, genes matter.

The real question should be why aren't more men. The reason is the patriarchy enforces super-strict hyper-masculine gender norms on men. Many would like to behave otherwise, but fear of the patriarchy keeps them in line.
