Yeah, asexuality is not experiencing sexual attraction to either sex. Some asexuals do still desire romantic relationships though, they just don't feel the need to express their love through sexual means (although they can do if they want to). Others feel the need for close friendships for that lifelong company.

Definitely have a read up about asexuality and see how you feel about it, even if you eventually decide it doesn't apply to you. There's also a big community boards on the internet where you can talk to lots of people in the same boat.
