No sexual feeling

This is a little difficult for me to word but I'll try my best. It seems that all over my body I feel very little, my nipples, clitoris and vagina whenever they're toched feel like nothing. Sex just feels like a hotdog in my nose, like yeah, it's in there but it's not doing anything for me, even when I masterbate I feel no pleasure. When someone plays with my nipples or clitoris I don't even notice because I feel utterly nothing. It's caused some problems in my sex like because I don't enjoy sex, I've never had an orgasm and it's gotten to the point where I just don't want to be touched, which saddens me because I really want to enjoy sex.  I was wondering if anyone had any suggestions on what may be the problem? Is my body just weird or insensitive? Is someone doing something wrong? Is there a way to make myself more sensitive to touch? Does anyone else feel this way!?
