I certainly believe that some people can choose their sexuality.
But just because you were a boy and into boyish things when you were a boy doesn't have anything to do with sexual orientation. Its really not very easy to see it in kids that young. I was just like any other boy but when those teen years came I fancied the other boys, frankly it disgusted me but I simply c couldn't help it. It wasn't a choice for me, of it was I likely wouldn't have been gay.
To be clear I never claimed that there are not homosexuals that cant change their sexuality.
I was just trying to make it clear that some people can choose and the existence of those people does not in any way shape or form make people similar to yourself illegitimate. You are what you are which is just a human being nothing more or nothing less. Yours and my sexuality in the large scheme of things doesnt matter. Who I am wouldn't be significantly different if I were gay, just small details. I would still be me just with a different sexual orientation. Male, female gay or not gay or whatever people are people and they are all basically the same. No orientation is the best, they just exist and thats that.
