Is there something wrong with me?

I'm 22 going to be 23 on the 29th. I never really had a boyfriend before, all of my friends have boyfriends and they make fun of me for being single. They all lost their virginity at 14 and 15 and I still have mine. Most of the time I can't go out with them because it's always couples and i'm single. I'm a really nice girl not stuck up or snooty at all I get along well with anyone. I see all these couples and people younger than me in relationships and wonder will I ever get my turn. I wish guys would give me a chance, is there something wrong with me?
