Non-ejaculation is the opposite of premature ejaculation. In the latter, the man ejaculates too quickly. In the former, he has trouble ejaculating at all, or can’t.

I’m not surprised that your lover is a wonderful man. Guys with ejaculatory problems often are. In fact, according to sex therapists, a major causes of this condition is the man focusing too intently on the woman’s pleasure and not enough on his own. This problem is quite curable, but the cure involves his being willing to focus more attention on his own pleasure.

Some couples can cure ejaculation difficulties with a self-help approach. I discuss it in the article on Ejaculation and Orgasm Problems. But you say he’s struggled with this situation his entire sexual life, so it might be too cemented to respond to self-help. I’d still recommend the article as background, but if the self-help approach doesn’t resolve things within a few months, I’m confident that a few months of weekly sessions with a sex therapist would.
