I had a brother who was gay. I was ten years older than he was, I noticed he was a little weird, he didn't want to play cowboys and Indians like his big brothers did. I noticed he was a little effeminate, but didn't think too much of it.

I came back from college one day with my buddy George, we visited the folks for a few hours, when we got in the car and left, George said "Your brother is a f*g."
I liked George, he was blunt spoken. My brother was 14 years old.

My brother grew up to be 6-5 and 225, looked like a pro football player, handsome. He just liked to be with the boys and never was interested in girls. He was born that way.
He never expressed any interested in wearing dresses or doing a sex change etc, wasn't interested in that.
