I can't orgasm?!

Tarryn
I've been with 3 guys and I'm 19 years old. My current boyfriend has been with a handful of girls that literally will come crawling back to him bc he gives the good dick. Like girls will STILL try to hit him up about it. And I've been trying to masturbate since I first started having sex a couple of years ago and I can't orgasm. Not even the guy I'm with now can make me orgasm. I've tried rubbing myself during sex, and I've tried fingering myself and rubbing myself when it's just me, and nothing! What's wrong with me! I've been told to relax and let your body take control and I've literally been so relaxed its insane and still nothing nothing nothing! Should I go see a gyno?
