Orgasm??

I have had sex a lot of times in my life and I’ve never had an orgasm. Whether he’s given me head, fingered me (fast or slow) or we had sex. And I’ve been with huge and small, good and bad. But none have ever made me. I can orgasm by myself but only with clitoral stimulation. I don’t know what to do because it doesn’t help to include that in sex. What can I do to help him get me to climax?
