If it were something based out of a lack of feeling rather than a surfit it would probably be a fairly innert part of the way I express myself.

I obviously don't know what it would have been like if I were born female, maybe I would still be a man. As of right now though, I wear men's clothes because I always have, wear a man's hairstyle because I have always have, use he/him because I always have... It feels more like inertia than a part of me, along with just being easier to conform to something I don't particularly care about, so if the ball had started off rolling the otherway... I dunno though. I suppose another explaination is that I'm just really secure in my "manness" I don't feel any need to convince myself that I am man, I just am one. Probably why I don't care about the "because" I just don't need it.

My answer to the initial question would depend on how much it upended my life I suspect. If I woke up, I was a woman and everyone remembered me as always being a woman, my wardrobe filled with skirts and I could slot right in, I think I'd just keep on trucking after some initial shock. But, if I had to explain that "I'm a woman now", buy new clothes, and all that nonsense, I think my answer would more closely resemble the parent comment.
