Why man?

Man is stronger than woman, and no one can deny it. I just don't want to believe that I can't be the man! Everytime when I saw my friends who can't protect themselves from being hurt by their boyfriends, I was so upset that I can't help them. They usually need a man not a friend. Ha...I feel tired of being a loser and the only thing I can do is to comfort them. Sure, those friends just need a tough guy! I know that! But why they choose men, not friends? I don't want to confess I'm a woman! Men can do and so do I. Don't persuade me I'm just a woman...It just makes me get down right away.
