is something wrong with me?

I know I'm not asexual, I know it as a fact. I mean.. I read porn and such and it turns me on (sorry probably tmi..) but I've never met someone I wanted to have sex with. Is that normal? I mean, I'm still pretty young I suppose, but al of my peers seem to know exactly who they want and what they wany when they want it. Am I too picky? Is it my problem? How could I fix it?
