Hi Elizabeth,
Before I answer may I offer some information to you that was in your post? TG,TS,IS etc is what we are, but it does not decide or have anything to do with our sexual orientation. Think for a minute where you point out some 'experts' say where a TG,TS,IS etc is attracted to person who is same sex as your birth sex. This seems to be based on some social concept to me. They seem to be saying that as women we should be attracted to men (and vice versa on the other side of the coin). If this statement held true then why do we have gay men or lesbians in the world? I am, as was just diagnosed, an IS and am turned off heavily by men. I am still deeply attracted to my wife, and her to me luckily. I have organs,brain etc of a woman, in other words totally woman but I am proudly lesbian. Hope this helps you.
The one thing that I would wish for is that my mom stops her denial and accept me as the daughter I really am. As for learning earlier, I feel God held it inside me hiding it as long as He did for a reason, such as I have my doubts my wife would've said I do if we knew earlier. My opinon mind you. And I would've probably blamed myself more for the rape I endured a lot more at the time (counselling would've changed that) and suicide would've been stronger I think.
