I don’t think homosexuality was more common in Ancient Greece than it is now in the modern western world. It’s just that it was heavily documented, it is right now. And as for the little boys thing, yes, that is disgusting. Sex between two adult men in private is fine, but sex between an adult and a child should lead to the death penalty for the adult. Not entirely sure if sex between men and teenage boys was accepted in Ancient Greece but my assumption was that it was rightfully condemned, but unfortunately happened anyway because teenage boys were drafted very young into the military.

Gay men will always be a minority. Simply because we do not want to have sex with women. I’d say we’re about 3-5% of the male population, which is a liberal estimate. The reason homosexuality supposedly happens more frequently in some societies than it does in others is simply because some societies cram it down our throats, some societies try (in vain) to suppress it, and some societies simply don’t talk about it.
