I haven't had a girlfriend my whole life and I'm 18, normal or not?

Its not like ?I haven't tried but now it just seems that I've got more important things to focus on such as getting a job, college, etc. But girls don't even ask me out or anything, I consider my self attractive, but not the best looking, I think I have a good personality (but not without its flaws mind you) so I'm unsure as to why girls seem to have a lack of interest in me. Help me out? Is this normal as well?

Let's clear one thing up, I have asked out girls before. So quit with the smartass answers

I'm not sure why this has been getting so much traffic recently lol, this post is 2 years old. So I guess to update, I have had s few girlfriends since then. So some of the advice worked. :P
