Um... wow. Thank you Dana and Fencesitter.. you both just made my day.
To answer some of the things FS wondered about: I have very small hands, so I'm not worried about that in terms of passing. I'm barely 5'7", so that would seem to work to my advantage too. I have been told that my voice is pretty andro, and that I could get by with little or no changes to it (not that it's overly feminine, but it's not deep either... I've even been told I already have some feminine inflections and tendencies in my speech).
It's funny. I feel like I do just enough to "pass" as a guy. I'm not overly macho or aggressive. I can be loud and boisterous, but that tends to come off as me being fun or dorky, not "manly." I swear a lot, but frankly so do a lot of girls. I often have to catch myself before I do something that doesn't match my "boy mode" presentation, like interacting with small children when I'm not with my own children, or complimenting a woman on her hair, clothing, or accessories.
I've heard the thing about my eyes before, and that I don't act like a normal guy in pictures... but it's always nice to hear again. Often, when I say I'm trans without being specific, people assume I am a transman. I take that as a HUGE compliment, because it usually means they saw some feminine quality in me even as I present as male.
I always get asked about my facial hair. It's still there for a few reasons: A) I'm not ready financially for lazer (since my hair is dark, that seems to be the way to go from what I've heard) B) I feel like I'm giving my face a beating when I shave it semi-daily. I feel like I should preserve it, if that makes a lick of sense. C) For now, I am living in the world presenting as male. Consensus seems to be that as a guy, I am more attractive with a beard. While I don't want to be a man, if I have to be one for now, I prefer to be attractive

D) The beard gives me a slight sense of security against my irrational (but growing) fear that, particularly when I'm around men, that "THEY KNOW!"
My other concern is my weight. I'm about 250 pounds right now. As a guy, I carry it well. Women don't seem grossed out by my body (at least that I am aware of); but I am a bit concerned about being this weight going into transition. I don't mind the idea of being a bigger gal AT ALL, but 250 pounds might be a bit much. When I finally get to go see an endo, I'm curious what they will say about my weight in regards to HRT, etc.
Thanks again, everyone... here's another pic of me with my daughter (whom I adore and can't stand thinking about being apart from... one reason why I'm somewhat tiptoeing into transition)
