Thanks for posting here in the transgender forum. It hasn't seen much activity recently. A short time ago, I decided to go off onto another website for my gender identity issues. But as it turns out, there's not much activity there either!
I'm an old man. And I live a pretty-much entirely male lifestyle at this point. But even when I didn't, I kept it all very much a secret. In addition to my various other problems, I've always been pretty socially anxious (except for a few years as a very young adult when I sort-of "exploded" out of my shell, so to speak.)
Except for that brief period as a young adult, I've always been a person who mostly just wanted to pass through the day-to-day world unnoticed. If you saw me walking down the street nowadays, I wouldn't look significantly different from any of the other older men in my neighborhood.
I do think, based on my own personal experience, that there can be a wide gap between what one can appreciate & feel comfortable with oneself, & what one can feel comfortable with out in public. At least that has been true for me. But, perhaps, it's simply a matter of getting out there & living your life out in public with your new look; and the more you do it, the more comfortable you will become with it. Hopefully that is the case. Good luck!
