Let me say, I had what you might call an "identity crisis" when I was between the ages of 13-15, maybe a little early, but I still had some very strong homosexual feelings.
I'm proud to say that through my faith in God, I've overcome those feelings, and I can now live a perfectly normal, healthy, Christian lifestyle as a heterosexual.
However, I never felt that I could speak to my parents about this, I've never really been all that close to them, but through a very obscure incident one day, I found myself in a position where I had to tell my mother, and doing that was one of the hardest things I've ever had to do in my entire life; she told me she still loved me, but cried for hours and offered no supoort whatsoever, she just sort of let me go off on my own while I thought about how miserable I had made her... and that was even harder because of the fact that ever since I realised I was "different", I had hated my homosexuality myself, knowing that my life would not be easy.
If she had completely disowned me or acted in the way that some of the replies in this thread talk about, such as "loving me less", I don't think I would ever have had the strength to look to God and get over this stage in my life.
Many people say, that you can't "change" and that if you have homosexual feelings, they stick with you for life, but that's not true. If you truly want to change, and have at least some small degree of support, or at least know that your closest relatives love you, it IS possible, but only if you have that knowledge of still being loved.
I hope that if your child ever tells you that he/she is gay, you will love them just as much as you always had, you don't need to accepttheir lifestyle or even pretend to be OK with it, but you do neen to make sure they know you love them, because without that, they will never have the strength to deal with their issues and they will never speak to you about anything important again.
God bless all of you (especially those who said they'd love their children no matter what

).
