Will people EVER stop thinking I'm a gay man?

I am considered well educated, my voice is slightly high pitched at about a tenor range, I practice good hygeine (I'm a bit of a germophobe because I study microbiology and bacteria all day) I've been told I dress well, although I just wear what's comfortable, and I've been told I have a warm personality. So..tell me, WHY does everyone think I'm gay?! Will these stereotypes EVER go away? If you are all of the above things I just mentioned, EVERYONE think I'm gay. The truth is, I'm not. I'm actually a transual female to male. So not only were people getting the wrong impression BEFORE my transition, they're STILL getting the wrong impresion AFTER my transition about my ual preference. Is there any way to fix this? Is it wrong for a guy to be short, well dressed, well educated, considerate, with a semi high pitched voice and STILL like GIRLS? It's getting to the point where I'm afraid to go out to the gay clubs with my old friends because gay men always hit on me.
