No Sex Drive?

I'm 22/m and I feel like I hardly have a sex drive. I'm a good looking guys, i'm not fat or anything, but I still end up in that dreaded "friend" category with women. I mean, god damn, I just wanna go out and get laid F the BS you know what I mean? But I can never "tie the knot" there's always something that happens, or something I say or do to stop me from hooking up with chicks. I was in the womb for 10 months, so I was a post-mature birth, I don't know if that has anything to do with it. I also had sex when I was really young, like 5 or 6. I regret doing it now, but I honestly had no say in it at the time. Just some random thoughts I threw out there.
