Guys this is an old post from 2001, so just pointing that out, even though the question is a common one that survivors ask themselves.
The simple answer to Mike's question is that there is no simple answer. No one has the answer I believe. At this point, science has no idea what makes a person gay, whether it be genetics, a mother's hormones or environment etc.
The majority of gay men are well adjusted and healthy people who have not been sexually abused. So I don't believe there is a direct correlation between child sexual abuse and being gay, even though as survivors we might think there appears to be a link. Obviously some straight survivors struggle with same sex attraction, but that is a different issue.
I'm happy being gay. However, it took me a while to reach that point, because I grew up in a world where being gay was bad. Like a lot of gay men it took a long time to escape that brain washing. I was also terrified of men because of the abuse, so that was a cruel irony in itself because even though I knew I was gay as a teen, I didn't let a man touch me until I was 27.
I finally accepted I was gay when I realised that being gay was not the problem. The problem was the impact of the abuse when I was a child. I know I'm gay because I am physically attracted to men, but most importantly I feel it in my heart on a deep emotional level.
It can be a confusing issue coming to terms with your sexuality, just be true to yourself and in time things will become clearer.
In the end it doesn't matter who you love as long as there is love.
