About 5 months into HRT, I got hit on by a gay guy at work. (In a VERY forward manner.) He could basically see my effeminacy.
And women actually seemed to get a little more comfortable around me. That's pretty much my experience, is that as everything softens up, people stop seeing you as being so much of a threat. Some people here have said that women started seeing them as being more attractive, but in my case people just started reading me as gay.
But that's kinda always been the case, is that even though I've never been into guys, people have just always assumed that I'm gay, and women have always been pretty okay with talking to me in a friendly manner... which just became even moreso as the hormones did their magic.
Now that I'm full-time, I've heard a couple of offhanded comments from friends of friends about how they thought I was attractive, but it's yet to become an issue like it is for most cis-girls, where they're constantly dealing with unwanted advances. I think people can still tell that I'm trans, though, so although they're nice to me, they don't see me as an attractive woman, just more as technically a woman.
