I hate to be a party pooper, and, please, don't get me wrong, I have nothing against this thread (plus reading a thread is just like watching a TV show: if you don't like it just change the channel), but: are we really defining womanhood by a certain body part?
It's like this apparent obsession with breast size and b cups, c cups, etc. A c cup won't make you more of a woman, and a double a won't make you any less. Women come in all different shapes and sizes. Your inside determines who you are: hormones, SRS, FFS will only make your looks confirm more to the accepted societal standards, and will also very likely help your inside show through, but they won't change your inside.
About the square jaw thing: I don't see how that would be a masculine trait: many women have it. And many of these "squared jawed" women are considered both beautiful and attractive.
Once again, nothing against this interesting thread.
