This suggests to me that being a man is important to him.
Which is a reasonable and likely interpretation, but certainly not the only one. I haven't seen gender fluidity in the Doctor so far either, but until recently I didn't see heterosexuality and from Ten and Eleven, I definitely do (possibly Four also, but only with Romana, not with humans). I know I'm skewing Doylist here, but part of my wish for a female Doctor is Doylist! And part of that, of course, is a wish for a writing team that will actually do justice to the character, which is improbable right now.
