When I was pre-transition and in early transition, I cared a lot about how to get T, what I could expect from T, how to be read as male more frequently, etc. I had a lot of worries about bathrooms, coming out, physical transition, and all that stuff. And even though I socially transitioned two years before I began physical transition, the social stuff tended to be less pressing. It was in some ways easier to deal with.
Now, however, things are different. I'm about as socially transitioned as it gets, I'm well on my way with physical transition, I'm stealth in some areas of life and selectively out in others. Now that my trans identity is no longer at the forefront of all of my day-to-day experiences, I'm starting to pick up on the social aspects of being a man a bit more. As an out trans man, particularly when I was around people who knew me before transition or when I was not being read as male, I was never really expected to live up to the norms and stereotypes of masculinity and maleness. People interacted with me like they always had. However, I am finding that people react to and interact with me in a vastly different way now that I am no longer known as "the trans guy" but rather as just another guy. People's expectations of me are different (when I apologized to my boss for a mistake I made, he thought I was giving him attitude), and the way that people, especially men, interact with me is really different (guys say the most disgustingly sexist things around other guys!).
However, on this forum, we have far fewer trans guys in late transition or post-transition than we do folks who are considering transition or just beginning it. I don't want to generalize off of just one person's experience, but I do think that this has something to do with the fact that social transition is not talked about as much. That's not to say it shouldn't be talked about - on the contrary, I think it's important to talk about all of this stuff, and I understand your frustration about the absence of this sort of discussion - but it just seems less likely to come up in this crowd.
