umm a ? about E D?

For now, he should assume it's the meds and not himself as such that's causing the problem.

Yes, seconding this. Granted, ED already has enough of a psych-out component. The last thing your DH needs is to develop a "complex" about something that probably is 95% medication related.

ETA: In the meantime, he'd better not have Oral Dysfunction.
