Well, I'd spend about four hours in the bathroom, playing -- oh, wait, you covered that.

First, I'd be quite depressed, initially. I'm someone who likes to have a clear sense of identity, even if I'm a variant thereof, and being male is a part of that; I enjoy it a great deal, and I think that I think in a typically male fashion (if that made any sense whatsoever). So there would be some adjusting before anything else happened.

Oddly, I think once the adjustment to the physical happened, the rest would come along relatively easily. I sense that for a basically straight guy, I have a pretty good handle on the parts of me that are "female". I could settle into the role with relative ease, in that I would have prominent parts of my personality being either "male" or "female", while guys - in general - tend to live outside the ambiguous areas of gender identification...thus, female seems almost a default classification. My guess would be that I would be bisexual, but I don't know for sure.

I've never tried to personify the female aspect of myself, except that efbq and I once created RPG characters of who we would have been if born the opposite sex, taking the name that we would have been born with as a starting point. So I was a slight redhead named Michelle.
