Ive been trying to research this. There isnt much on it. Its a big effin deal if a man doesnt feel like a man - yhey research the buck out of it - absent father? Overbearing mother? Ohno what do we do?? - but if a woman doesnt feel womanly, who cares? So far im finding maybe your mother wasnt around enough for you to learn how to be a girl, so too bad. That definitely works in my case - i even asked my dad if we could ask her to move out - i thought my mother was a boarder and i told him she was mean to me. I was like two. He explained to me we had to keep her. Anyway not a lot of bonding and identifying happening there. So its hard to pinpoint what did NOT happen. Thats partly why neglect is not benign.
