If I ever had it to do over again I would just get everyone that knows me together for a huge party and get up on stage in a pretty dress and tell all those shocked faces at once that yes I am really a woman deal with it, and then sneak out the back with the car and my boyfriend waiting to take me to the airport. Let them figure it out. Kind of like Bilbo did in lord of the rings, only he was not a woman, I don't have a ring to make me invisible and I would go to Thailand.
anyway,
it sounds like everyone is going to know about you soon enough. Your freeno more closets for you. You'll get used to it in no time.
