The big O

So I have a question....does anyone have trouble orgasming? Like when you’re having sex with someone but you never orgasm.

It’s easy to do get myself to orgasm but I’ve never O’ed while having sex with someone. Is there something wrong with me? I’m soooo scared to ask someone about this because I feel like something is wrong with it. I mean I usually have amazing sex but i just can’t ya know....please someone explain this to me.
