Congrats Alice, that's a big, big step for you. As far as presenting as a "guy", of course you can do that while you get your facial hair removed. I've done it since last July. You will probably get comments like:
"why is your face red/splotchy?"
"you look younger, what did you do, get a haircut?"
"you look so different, but I can't figure out what's different about you"
It takes a while for the hair removal, so definitely that out as you take each step. I like that you are going slowly, especially in light of your feelings and how you started this whole thing. You have had a lot of doubts and questions and you've been going slow, which is a good thing! Keep up the good work, Meghan
