Brayton,
Hmm...well, I guess it's good that you're able to identify your prob, and I'm glad that you still choose to reach out.
Just for my clarification though (sorry, it's early in them morning), I presume that you are saying that your self-loathing (i.e. hating yourself--because you're gay or perhaps the abuse?) is what causes you to be uncomfortable with the so-called "gay community" (whoever that would be). Additionally, you are saying that you do not feel comfortable talking about your abuse with this "gay community." In addition, you have generally found more support from the "straight community" than the gay one.
Hmmm...assuming that most of these are correct. Just a few questions to maybe ask yourself:
1) Do you feel like you've separated the abuse and gay issues (i.e. their unrelatedness)? I say this because this was a big hang up for me which caused "me" to freeze up and to just get overwhelmed. As soon as I separated them, I was able to fully embrace my sexuality (stopping a sort of "self-loathing" I suppose), especially combined with support from a religious community of their acceptance of my monogamous, long-term relationship kinda lifestyle.
2) Do you feel as though you have enough gay friends in "real life" (i.e. outside say internet, etc.,). The reason I say this is that this too is a big hang up for me. Right now, I'm still very uncomfortable with "coming out" and so do not hang out in gay circles outside of when I am with my partner and his family/friends. In fact, I have little to no friends in the "gay community" who I found on my own and who I see regularly. Most of my friends are straight. Thus, it may be natural for me to say that that my straight friends are so supportive when in fact it is because I do not know of enough gay people who are truly representative of the community (and by this I mean "know" gays/be friends with them rather than just acquaintances at bars, etc.,). I know it may be a stupid analogy, but it's kinda like the whole overgeneralization thing driving us to then fear of a "group" of people. (perhaps, just perhaps)
Now, do not misunderstand...this goes both ways. For me, personally...(despite my straight friends' consistently welcoming reaction), I'm still very scared of the straight reaction to this stuff, and am hardly out (I pretty much just leaked some info and got people to talk). In fact, of late, I've detached myself from some straight friends (though am reinforcing other straight friendships with whom this homosexuality thing is okay for sure). I know that's not a good thing, but I've got a lot of my plate right now. I will work on those stuff soon...
Anyway, I guess, I'm saying don't be so hard on yourself. I personally envy your comfort factor with the straight community--and think that to be the bigger hurdle (than to have the comfort factor with gay guys). Despite your discomfort with being gay and having been abused, you at least have the courage to speak openly about it to your straight friends. Your half-way there I guess--all you have to do now is separate the abuse and gayness so that you may perhaps open yourself up to the gay community (including about the abuse--in fact, you may be surprised to hear how many gays have known people who have been abused). Indeed, the gay community, from my experience, IS welcoming and friendly. In fact, they can be overly community/group-oriented because of an inherent feeling of still being marginalized. Yes, there are exceptions, and plenty of them, I'm sure...but just is with any other "community" that is small and marginalized, you may have to go digging past the egos, the self-defense mechanisms, their own hurts, their own distrusts, to finally find that "perfect" niche for you.
AIght...I'm rambling...I should go...but hope you can make some sense out of it. Later.
