It's just great that he's open to the possibility that this could be his issue.
As to how does one change it...well a Neurological Psychologist could be a start...to literally retrain him how to think about this issue. I can see where that could have really helped my H, but the Psychologist he saw #1 wasn't getting the truth of things from my H, and therefore #2 didn't address teaching him how to think differently about this issue. He did help him to stop assuming I meant things when I didn't, he did help him learn to stop thinking of me as his enemy, and he did help him learn to stop automatically jumping to the defensive with me...when there was no need for it.
However, a sex therapist can probably also teach him how to "think" differently about this issue. I'm sure someone with that specialty should have the ability to help (but I'd made sure anyway).
Best of luck to you two!!! Sounds like things are looking good for you!
