I'm asexual too. Definitely a normal sexual orientation. I've just never wanted to have sex...

Here's a link for you.

AVEN

As has already been stated, asexuality is definitely a possible sexual orientation. Some asexuals want romance, but not sex; others would prefer friendships only; some have physical sex drives that they don't want to satisfy with other people (no desire for romance). Asexuality is quite varied... just as hetero and homosexuality are. There's even an in-between orientation tentatively labeled "grey-A", for somebody who is very slightly sexual... someone who doesn't mind having sex but won't initiate it; somebody who doesn't want to have sex more than a couple of times a year; that sort of thing.

The only time I'd worry is if you'd had a sex drive before and somehow lost it, or if you never went through puberty to begin with--those are indicators of physical problems--but you're nineteen and have never wanted sex.

You might meet somebody you want to have sex with in the future; but for now, whether or not you ever do, you're functionally asexual. It's not something to be ashamed of, though it's less well understood than the majority hetero/homo orientations. From what I can gather, asexuals are about 1-3% of the population. Many aren't actually virgins--they tried it because it was expected, and didn't like it, for example; or they're in a relationship with a sexual person and have sex for that person's sake. So the genetics get passed on, and a new generation of asexuals grows up thinking, "How come I don't want to have sex like everybody else? Am I defective?"

You're not. You're just in the minority. And you're in good company.
