Kinda struggling

For years, I've struggled to masturbate. I know how to do it but nothing ever happens. I've been with my boyfriend for about 6 months, we're intimate and trust me y'all he'll spend an hour to please me, he always prioritizes me but thing is I can't climax! I've never been able to cum. I've tried absolutely everything in the book. I can't make myself cum and my boyfriend can't help either. It's not a him thing cuz even before he was in the picture like I said I've never been able to hit a climax. I've tried vibrators, dildos, different positions, etc. You name it I've done it. And now it's finally getting to me and it's frustrating. Help?
