For the record, I don't think something like chemicals or whatever make people gay, I actually believe something that is for some reason more inflammatory. The religious aspect is a major driver. The prevalence of homosexuality is a social thing, sexuality is largely not innate and is learned behavior. I don't believe Roman society as it existed for example would be possible if it were otherwise. A society with institutional pederastry, where men were often expected to engage in sex with other men, one where there wasn't even a word for homosexuality, but that had strict codes of sexual conduct nonetheless, is absolutely impossible if sexuality were innate from birth in the majority of the population.
