I've never felt sexual attraction to someone?

I'm 16 and I have an active sex drive (as in I feel compulsion to have sex) but I'm not really attracted to any particular person? I'm bisexual (I like having sex with both men and women and I'm pretty good at being intimate, so I don't think that is the problem ) but the only thing that really gets me going is certain scenarios (admittedly I'm pretty kinky). I mean yeah, some features are nice to look at, but I don't really see any type of bodies as sexual and the idea of having sex repulsed me most of the time.

The closest I've ever been to feeling sexual feelings is when I was having sex with this girl I think I love, and she was in the middle of an orgasm and I felt a sense of accomplishment and happiness because I did that. But it was more like the type of thing you feel when you give someone a gift.

Is there something wrong with me? Do I need to see a doctor or something?
