Yeah... I definitely agree with everyone here. HRT really is something that can completely change you, and you have no idea where you'll end up sexually as a result.
I started HRT being attracted to women exclusively, but now 2 months in, suddenly I'm starting to feel somewhere between bisexual and asexual. I just don't find other women to be that attractive anymore. I still stare from time to time, but mainly it's because I'm "studying" them, trying to see what it is that makes them seem feminine in the first place, and it's just not that same gut reaction where their beauty inspires me and makes me want to write poetry and thank them for just being alive because they're so beautiful. Yeah, I don't get that anymore. I can still recognize beauty, but it just doesn't do it for me in the same way that it used to. And at the same time, I am definitely starting to see something in men that I just never saw before. As I'm starting to feel a bit weaker, strength is suddenly becoming attractive to me. I'm still not quite at the level where the attraction would be enough to base a relationship off of, but the feelings are definitely being planted there. So who knows where I'll end up? All I know right now is that my feelings are much different than they were before, and they are still being changed and molded by my new hormones.
So yeah... it's a process. A lot will change, and who knows where you'll end up as a result? Just go with the flow, and let the estrogen do its thing, and you'll know soon enough.
