We don't live together. He has told me that he's afraid of being judged for us just having sex. I imagine it's more of a cover for feeling embarrassed or ashamed to go admit to someone that he has premature ejaculation. And also facing up to the fact that is problem is somewhat severe and has been lifelong.

I'm not sure I could convince him simply by telling him what a therapist said. You have written out a more solid plan than I could think up, so thank you for that. The only AASECT certified therapists in the state are an hour away unfortunately, making it more difficult and more anxiety-inducing for me to set up an appointment and go by myself. I might try to convince him one more time to go with me.
