I probably pass 90% of the time now. Also, I realized I accidentally hit 1-2 instead of 3. I just clicked the wrong circle, so squint when you look at the percentages of people.
I'm almost at 3 months now and it was pretty evident that most people think I'm a dude (even if they don't think I'm 22). I was flying a lot this weekend and I wasn't addressed as "she" once.
I'm lucky I don't have to deal with boob problems, though. I mean, I have some, but they're easy to bind or I don't have to bind at all (because I'm heavy so they blend in). I think I'm kind of on the cusp of passing and people look for something tell-tale that would give it away, like boobs. Since there isn't ANYTHING when I bind, it's "sir" and "young man". So... yeah. But my voice just dropped into an acceptable male range recently. Plus, I squeak alot while talking. Before that, I guess people just assumed I was a female with no boobs.
Also I've been graced with what my mom calls "swimmer's shoulders". So my frame is wider than most female bodied people's, though I'm 5'7" (which is nice, but I'm not like a 6' anomaly or something).
It all just comes together, I suppose.
