I never dated in high school, ever. I was one of those girls who was lots of guys' friend but nobody's girlfriend. I never even really kissed a guy until freshman year of college. (There. I said it.) Although I have kind of made up for lost time, I have only had one relationship last more than a year, and even now I'm still kind of shy around guys...well, I talk to them but I am chicken to come out and tell them I'm interested.
Don't worry...you are hardly alone.
