I'd have to say that for the most part my interactions with people who identify themselves as part of the LGBT community have been positive. I think because I am an Aspie it is easier for me to understand their claim that sexual orientation is something you are born with and not something you choose or easily change. Although I do believe that sexuality is a spectrum and that we humans, being highly intelligent and curious, are more free to experiment with our sexualities than other animals and that it is possible for someone to decide on the basis of experience that they prefer one sex over another. I don't consider that a true orientation, however, but a preference.
I myself am asexual in that I am not really interested in having someone enter my body nor do I particularly care to enter theirs. Until all this discussion of same-sex relationships came along I pretty much took it for granted that I was straight. After all, that was what my culture said I was and I saw no reason to question it. In thinking over the matter I'd have to say that I am neither straight nor gay. Nor bisexual. Actually when it comes down to it, my sexuality is nobody else's business. I think the only time anyone's sexuality should be other people's business is if that person is sexually attracted to children or is otherwise using their sexuality in ways to hurt others. What consenting adults want to do with each other, as long as it is in private, is their business.
I have friends in the LGBT community. However, I do not want to become identified with that community because I feel that it would impoverish me socially. There are no openly LGBT people in the other organizations I am a part of, and if I were to become known as "one of those" (even though I am not), I would find myself interacting primarily with LGBT people and lose the range of contacts that I now enjoy. Since I don't share any of those orientations, I'm afraid I would find that in time I would not fit in well with the LGBT community, any more than I could fit in with the church that I was in. I don't want my social life defined by sexual orientation, mine or others. Right now, I am accepted pretty much wherever I go. I could not do that as part of a community defined by sexual orientation, even asexuality.
