Understanding one's gender identity?

Hi. I asked this question before but i got a lot of negative feedback, so let me try and rephrase it this time. I asked :"what is the biological difference between ed individuals and individuals" (now for some background info). I am a gay male teenager who has only recently( about 7 months ago) come into the self awareness of my ual orientation. I am comfortable with the fact that i am "different" then 95% of the planet, as i am primarily attracted to members of my own . But what i have been wondering recently if its possible i may be ed? After thinking about it i have realized that as a kid (and still), i have exhibited some very gender non-comforming behavior. I dressed in drag once or twice when i was little, and have recently started doing it again alone, for fun. I kissed a boy in kindergarten, hated competitive sports, the usual. I know that this type of behavior is typical among gay men and women (especially throughout childhood and adolescence). But what i was wondering (now getting back to my question), is what makes the difference between typical gay male/female gender non conforming attitudes as a kid, and a ed individual. why do some gay men and women change es while others (who exhibit the same gender non conforming attitudes as children AND adults,) dont?. is there really some biological difference btwn. the brain of a and a ual, or is this a matter of nurture?, choice? I've thought about it and come to the conclusion that im comfortable being somewhat "postgender". Living my life biologically as a man but accepting the fact that i dont really fit perfectly into any category. That im definitely not a "bro", but not one of the girls either in some respects. That gender exists but isn't a strict binary, and i dont have to fall on one side or the other. That instead of trying my whole life to be a women, and dress in drag. The more fashionable thing to do is to just dress how i want, but WITH my male body and genitalia. Thats true post-genderism. and to me (a huge feminist i might add), that is the more feminist thing to do, since i've always felt like transvestites (and drag queens who are not ed), are trying to be an archetype of 1950's overfeminized womanhood. Anyway back to the point. So my question is now. "is my brain that of ed individual or simply a gay man?"
