I have noticed a general, over all "settling into" my female body, no body hair at all to speak of, even on my arms and legs; my breasts have gotten fuller, as have my hips. My belly has as well, unfortunately.
One of the most interesting changes is the remapping of the brain- I can touch various areas around my labia, clitoris, or even up inside, and that is exactly what it feels like to me- what it is now. There is no sense whatsoever of "oh that used to be this or that", because in a very real physical sense it is what it is now and not what it "used" to be. Inside my vagina feels nothing like what I expected it would before surgery, and nothing at all like a penis. Not only does the brain remap itself, but also the nerves and the various areas of the skin, once grafted together, grow and change over time to become only what they are now. It isn't "penis skin" in the shape of a vagina, it becomes simply vagina skin and meaningless to think of it any other way.
As the body heals from surgery, so does the mind. More than there simply being no vestiges of penis left, I can't even remember what it felt like to have one anymore- I only know what it feels like to have a vagina. I mean, of course I remember that there was something else there in a strictly academic sense, but that "feels" so foreign and alien to me because the the old sensations have been completely overwritten by what is there now. I think this is why we forget so readily, because the brain becomes literally no longer physically wired in those terms.
