Scared to have a girl.

Okay... I know what you are thinking, but I am terrified to have a girl. I am so afraid that I wouldn't be a good mom to a girl. I am not/was not a girly girl... someone who dated a lot or knows anything about make up. Let alone having to deal with proms and periods. I LOVE having a son. I am very much wishing for a boy and I'm afraid I will feel deviated otherwise. I know a healthy little peanut is most important, but I just don't want to screw up a little lady. :-(
