romantically retarded?

I'm starting to think that I completely LACK the ability to have romantic feelings. Three or four really great guys have asked me out in the past few years, and the idea of dating any of them (or dating ANYONE, actually) was really, REALLY unappealing. I haven't had a crush on anyone (anime characters don't count XD) since I was a little kid. I'm the only person I know who's never even gone on a single date. Is there something wrong with me? Am I incapable of forming an attraction to anyone? Jesus, I hope I'm not asexual. It wouldn't be bad, but it would make me feel so awkward. Not that I'm not usually awkward anyway. But... I'm almost 20 years old and I've never once had any desire to be in a relationship. Hell, lately I do whatever I can just to avoid being around people other than my family and a couple of really close friends.

I'm probably just overthinking things again. 

All that aside, I'm almost better! I've been sick for almost two weeks, and I think I'm almost completely better now 8D I'm so happy!
