Dang media. The world loves to define what "womanly" looks like and people buy into it. Take my wife for example. She is 5' 6" tall and broad shouldered. The only way she would ever weight 115 lbs is if she was on her death bed, but no matter how small she looks, she won't ever be "skinny enough". Just because of some insane and unrealistic view of beauty that we've developed in this society.

This, to me, would be more of a body-morphic issue really. I think you should get some real views of women and see that you really are quite womanly. It's just a feeling. Maybe even a little therapy?
