1) Very limited sexual market.
A lot of Greek/Roman/Arab/Chinese/Japanese homosexuality was based around attraction of an older, usually unmarried, male toward a pubescent, androgynous male. The adolescent was often forced to wear dresses, makeup, and wear long hair to further enhance his similarity to a woman - take the chigo, for example. This was confounded by the fact that often the adolescent male wasn't yet a male proper socially speaking, but hanging in a limbo between childhood and manhood. See chigo, once again. As long as the adolescent wasn't initiated into maledom, it was Ok to have sex with him. After the initiation, which corresponded with the development of umistakable male featureus, it turned socially reprehensible.
In this case, the limited availability of females created the condition for homosexuality to thrive. Another such example, but on a smaller scale, are the all male boarding schools, where yaoi like romance happens often.
The open sexual market made this form of sexuality unnecessary.
2) Repression of sexual desire leads to it expression in perverse forms.
Judaism and Christianity and Buddhism have incredibly strict sexual rules for monks with regards to females. If you want to be a monk, you have to repress the natural urge to stick into a female. But lust is such thing that, if you block it in one place, it will erupt into another, sometimes with violence. Women being forbidden objects, lust obviously shifts to the next closest thing - adolescent males who look cute, that is, feminine.
Hence, all the problems of the Catholic Church. Religions that allow marriages don't have such a problem.
The image itself is very feminine. Feline. Long nails. Soft features. Feminine gestures.
