Advice on sex life

Ok so I have a weird issue. I’ve been dating a guy for a while, we have recently started having sex. The sex is mind blowing, but only for me. He doesn’t orgasm. No matter what I do. I’ve asked him if there’s something I’m not doing ect. Turns out he’s never orgasmed since he broke up with his ex (5years ago). He can reach climax when he’s by himself, just not with me. Has anyone had an issue like this?
