I get what you're saying about same gender friendships and there's nothing unnatural about that. It simply doesn't impact on a latent inbuilt attraction.
"Latent inbuilt attraction" ?
Yes, your socialization does impact your later sexual activity.
If you were socialized in ancient Greece...
Are you saying you didn't find girls attractive when you were a child and saw them differently to other boys?
I remember in preschool, the boys used to all ask each other, "Which girl in the class do you want to marry?"
The correct (socially approved) answer was, "None, gross." One kid used to always say, "All of them." Everybody thought he was a weirdo. I went to a Jewish preschool, though. Maybe that's a Jewish thing.
No, sexual attraction is not governed by morals. You can argue that as much as you want, it won't make it any the more true.
Yes it is. Partially.
Men and women will often find someone more attractive when they find out they're single.
Many perverts even find someone more attractive when they find out they're married.
If I was raised by wolves I probably wouldn't have bought anything much...
What I mean is, the culture tells you "this is how you ought to get your kicks."
If you'd been raised by ancient Greeks, you'd get your kicks a different way.
