My pleasure.

It's what I'm here for.
If I had to guess, the lack of confidence could be a major player. That is, ironically, something I understand fairly well.

If he doesn't feel like he's...up to task, I suppose, that could be a huge factor in why he doesn't seek sex more: if it makes him feel uncomfortable by virtue of lack of confidence, he precludes the issue by avoiding sex.
I hope the talk goes well, and do let us know how it goes.
Hugs,
Harley
