My friends have "more experience" than me?

We had a guys night on Friday. I am the only one that wasn't in the Frat they were in, so they were all talking about the girls they slept with in High School and college. We are a few years out of college now but I haven't been with nearly the amount of girls they have nor was I having sex in high school. They all hate being alone, but I don't mind it. I never needed a gf during school because I wasn't the frat type I was kind of a loner. Is this alright to feel like I don't fit in sometimes?
