Isn't being gay all in the brain?

Answer 1

There is an area a bit lower that has quite a bit to do with it also. Seriously though, yes, who we are, what we like, gay, straight is all in the brain. The body is just sensory imput for the brain.

Now if you meant to say it's all in a persons head. That they think they are gay and can change or that it is a choice, then NO, it's not in their head. People are who they are. Some are gay, some straight.
