Is Being Gay Hereditary/Genetic?

[FouTight]

I feel as though homosexuality is in the same vein as a fetish. Albeit, to the extreme, but I think it's not to disimilar from a fetish in that certain people are just aroused by one thing or another, some times it's pretty unsual.

But I also think it's hormonal, because in a large number of cases, homosexual men tend to be much more feminine then their heterosexual coutnerparts, and vice versa for women.
