I believe, for the majority, it is NOT a choice.
But,
How come there are gay men who have children when they were / are marred to women?
Obviously , they were able to "function" in a hetereosexual capacity.
Also, some cultures deem being the "pitcher" normal, but the "catcher" gay. This I don't understand.
Also, homosexual sex in prison among otherwise heterosexual men? For the victim it is rape, but a willful act by the perpetrator; unless it is consensual.
