Struggling to orgasm..

My boyfriend and I have been together for 5 years and he has never been able to make me orgasm, I can make myself orgasm with a vibrator and rarely my hands but I struggle to do that without porn. I used to have a bad addiction to porn and it wasn’t good for our relationship so I stopped. But it is so hard for me to orgasm, and it’s hard cause I don’t know how to show him how to make me orgasm when I barely know how myself. And most of them are kinda meh, I have maybe gotten two or three really amazing orgasms. Is it bad that he can’t make me orgasm? And should I be communicating anything to him about my frustrations not being able to orgasm? Our relationship is truly amazing and I am so unbelievably happy with him so I am not in any way frustrated or upset at him.. more confused at myself as to why I can’t come so easily.
