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. The theory holds that the same genetic factors that induce gayness in males also promote fecundity high reproductive success in those males' female maternal relatives. Through this trade-off, the maternal relatives' "gay man genes," though they aren't expressed as such, tend to get passed to future generations in spite of their tendency to make their male inheritors gay.

Battling the 'homosexual agenda,' the hard-line religious right has made a series of incendiary claims. But they're just not true. Ever since born-again singer and orange juice pitchwoman Anita Bryant helped kick off the contemporary anti-gay movement some 40 years ago, hard-line elements of the religious right have been searching for ways to demonize gay people — or, at a minimum, to find arguments that will prevent their normalization in society.
The handkerchief code also known as the hanky code , the bandana code , and flagging  is a system of color-coded cloth handkerchief or bandanas for non-verbally communicating one's interests in sexual activities and fetishes. The color of the handkerchief identifies a particular activity, and the pocket it is worn in left or right identifies the wearer's preferred role in that activity. For example, a dark blue handkerchief indicates an interest in anal sex , and wearing it in the left pocket indicates a preference for being the insertive partner. The wearing of colored bandanas around the neck as a practical accessory was common in the mid- and late-nineteenth century among cowboys , steam railroad engineers , and miners in the Western United States.
