I have told exactly one person. He's a good friend of mine, and really cool about it—he more or less said that he doesn't care who I do, so long as I'm getting laid semi-regularly.
I am so glad to have that friend! I first knew when I was 12—straight porn really didn't have an effect on me, unlike all the other preteens I knew. I dated a girl throughout high school, and we had a great relationship, but the whole sex thing left me confused (hell, I don't know the intricacies of a vagina—I didn't have one to practice on, myself!) There was one day that I tried telling my mom that I had a crush on a guy friend. She said it was just a phase... there was another instance in which she was making fun of a gay guy on TV, and I got angry at her for it so she asks, "What, are you gay?" and I said something to the extent of "I can't be, you won't love me that way!"
She never really said anything after that, except she keeps mentioning how she wants grandkids and a daughter-in-law. On one hand, I feel terrible that I can't deliver that for her—there's nothing that would make me happier than to be able to have a wife, 2 kids, a golden retriever and a 4 bedroom house with a white picket fence. On the other hand, for me to actually have a wife and two kids would be totally unfair and dishonest to both them and me. And I don't think I could put a family through that.
I guess the long and the short of this is that I've thoroughly enjoyed reading all of these stories. I couldn't be happier for each and every one of you for whom the situation turned out well; for those for whom coming out was a difficult process, I understand your angst completely.
