Advice please

I’ve been seeing this guy who is in his 50s and I’m just about to be 22. Age has never mattered to me because I’ve always dated older men, but never this much older. I don’t care what anyone thinks because I’m genuinely happy! He’s amazing! He doesn’t only tell me how much he cares, but he shows it and he never makes me doubt or wonder. He wants to take us to the next level and eventually make it official which of course I’m happy about. He’s already had a vasectomy and he said he’s willing to reverse it so we can try to have a baby, but he also said he’s in no rush to have a baby. He’s not getting any younger though.
