Actually, I think you are just reflecting the experience of your own set of friends. All studies that I have seen doen on sexuality point to the fact that most people have, at one time or another, been attracted to members of the same sex.
I'm a 47 year old man. I cannot remember EVER feeling the slightest attraction to another male.
You help me keep score now.
Those same crap reports say that gay/les pop is 10%. Real numbers say 3%. The world used to be flat too.
