I have a problem

Back store: I’m 20 years old and have been in a great relationship for about a year with him. I’ve only have 1 other sexually partners before him.

So I have never had an orgasm! 😭

I don’t know what I’m doing wrong.

I feel bad that he might think he sucks because he can’t get me off.

Any recommendations on what to do/positions/masterbating?
