I'm not sure if this is completely normal, but I cannot stand masturbation.
To me, it feels like I've put a stick inside of me. It has never turned me on and I've tried on multiple occasions since I was 13. I can't stimulate my clitoris either.. It does absolutely nothing other than make me irritated.
Also, sometimes (more like most of the time) I can't "feel" sex. I can feel my SO go in, but then there's just nothing. The first time I ever had sex, I couldn't feel anything and I just started to assume that was how it felt..
