Is it normal to have so little contact with girls?
I'm in my late teens now, and have never really had any contact with members of the opposite sex. The longest I have talked to a girl for is about five minutes, and that was just because she happened to be my partner for a school project. Not long ago, a stranger at a meeting came up to me and tried to make small talk, but I found it impossible to maintain eye contact for more than a split second, and felt myself getting hotter and hotter until I was sure my face was red all over. The girl must have assumed I was not interested, and probably went on to discuss the weather with someone else. I am already shy around male strangers, but having to talk to a female of my age made me nervous beyond all reason.
My self-esteem is extremely low, and I am afraid to approach girls since rejection would further wound my ego. I also realized quite recently that I have high-functioning autism of some kind, and though this has helped me learn a great deal about myself, it has also broadened the line separating me from my peers.
Is it normal to be this awkward, and are there any ways to overcome my phobia of the opposite sex?
