After I started "passing" because of T, I became a lot less invested in trying to imitate stereotypical male behaviors. I realized after that that it didn't necessarily make or break my presentation. Mostly, I'm just viewed as a gay male due to some of these leftover qualities perceived as feminine, which I am, so that's okay with me.
I just wanted to interject this to let you know that there is not necessarily any form of behavior that will make or break your passing. It may help in some scenarios, but being yourself will not make it so you NEVER pass if you prefer to do that.
