Hello Zincoff
I'm an old user here at Susan's. I left but re-joined, since I specifically wanted to reply to your post.
Your situation is far from unique - my history was similar to yours. Firstly I want you to know that there is plenty of time to deal with your situation, so work on keeping calm and steady. Whatever path you choose, I strongly recommend that you keep a cool head, a strong desire to understand yourself, and that you maintain an absolutely positive attitude at all times. This last point is so fundamental that I cannot emphasise it enough.
As Ms Grace states, a good therapist is a wonderful thing, as long as you are honest with yourself during your sessions. This may take a few sessions, but it's really worthwhile and - whatever path you may choose - you will understand yourself better, which is always a good thing! You need to have a good vibe with your therapist, so do consider changing if the person doesn't work for you after a few meetings.
Some observations: it's very hard to have a gay identity and make a life as a gay man in a gay male world when your core identity is really that of a transgender woman. I think that some of us deal with this by sublimating our transgender sense of ourselves into a gay identity and, by doing this, we hope to find a halfway house: begin a gay man with another man may be easier than becoming a woman in order to be with a straight man. I, too, found that the gay world did not fit me, even though I liked gay men. But as I released my mind and gender identity, and thanks to one specific boyfriend, I came to realise that at my core I wanted to be a woman with a man. (I know that this whole bit about releasing your mind sounds like something from Matrix, but it's really fundamental!)
My advice is to embark on your exploration calmly, and see what you find. Nothing is predetermined, and you may find that both your overall happiness and OCD will improve once you find your correct path. You have plenty of time – really you do – so please remember this.
Does this make some sense?
Hugs
Julia
