Well, personally I think my gender transition has helped me realize that gender really isn't something that matters to me when I think about love. I thought I was a gay guy during high school; since my transition (and staeting HRT, this should debunk the whole BS "HRT changes your orientation" myth) I've mostly dated women. It doesn't have so much to do with what sex or gender I prefer, it's just that A. I happen to dislike excessive body/facial hair, and B. I tend to be more compatible with women personality-wise. I have a hard time dating people who won't be willing to respect the fact that I want to be equals, and men-well, in our society it's hard to find a man who isn't intimidated by someone who wants to be his PARTNER, not his GIRLFRIEND. I don't know. If I passed a bit better (hopefully I will once my hair grows out) I'd probably date more men, but it's just rarer for me to find a guy I'm into. It's really not about sexual orientation for me though...it's just who I tend to *click* with. I should probably add that I'm pretty much asexual; I'll have sex if someone wants it, but it doesn't really interest me.
So, yeah-transitioning has made me more aware of just how inconsequential gender really is, and I've just sort of...disregarded it. I've fallen in love with guys, I've fallen in love with girls, and I've fallen in love with folks who aren't either. After what I've been through, the differences seem like pretty small ones.
