Nero, this is a tough one.
A voice in my head says Be careful what you wish for. I've always had a problem with the separation of body and soul. They are interconnected and affect one another greatly.
It would make a difference, whether I had that body suddenly at my age, or started out in the other body. Would all my genes save the sex-related remain the same. With my genes, I doubt I would be a model, though my mother modeled swimwear on Jones Beach; the catch being, it was swimwear her father was trying to sell during the Depression
I suspect I'd say Girls Rule, never question being a woman, and, regardless of neuroses, never be aware this forum existed. I know I am already more comfortable following, than leading, on the dance floor. On the other hand, most of what I like to do, I can do now. Read, write, listen to music, work for social justice, cook, eat and drink, care for children, love my partner, hike. That is probably what makes me an androgyne rather than an mtf.
And now my wife is calling down looking for her supper,
