Can’t climax

My boyfriend and I have been together a long time. We have only had sex a handful of times. And we were both virgins previously to us getting together. We have great foreplay, the sex is good... but I have never ever ever once been able to orgasm. Even from masterbating. I dont know what’s wrong. But it just doesn’t seem normal. Sometimes I get wet, and I’m horny, and I’ll think okay let’s do it let’s hope this time I do and it never happens. What do I do?!?
