It's not unheard of, but 19 and still bf-less?

I will be 19 next month and the thought that I have yet to have a boyfriend, or even a date had occured to me. Now, I am constantly being told that I am attractive, and I am definitely not a ditz in any way. I make people laugh, and I am only opinionated when I need to be. Im honest, and caring....and yet, still without a boyfriend. Is there something im doing thats wrong, or that is just wrong with me?
