It's definitely not abnormal to not have been in a relationship by the time you're 23. You'd be surprised by how many people are in a similar boat.

I agree with Lee though, don't worry about what you look like, it's all about self esteem. I once had a friend say that "confidence is the sexiest shirt someone can wear."

Also, you might want to look into theories on the Law of Attraction. I don't know how much you believe in energy, but the idea of it is that what you put out into the universe is what you get in return. If you put out self-confidence, positive thinking, and truly love yourself, you might be surprised at one turns up.

Seriously though, stop focusing on the guys and first figure out how to truly love yourself.
