Well, we talked about it last night and, yes it is the SA thing, however not in the way that I thought.
As most people that are in a relationship with an SA, sex is just about all they think about 24/7/365. Now combine this with performance issues and you have my WH. He is freaking out about not being able to 'satisfy' me and has been researching the reasons why a healthy 42 year-old would have performance issues (also looking at pictures to see if it causes any type of reaction). He showed me the search history on his phone and all of the sites are the ones that only have still photos and not movies, which is not great but it could have been worse. I honestly should have known because of the amount of talking he was doing about his 'research' and his issue.
I think his performance issues are a combo of guilt and RLS medication that's main side effect of long-term use is sexual dysfunction. He thinks is it a combo of medicine and everything else under the sun.
He made an appointment with his urologist to make sure there is no medical reason and he called his IC to tell him that he wants to focus on his SA issues for the time being. He is being proactive, which is great, so I'm considering this a bump in the road.
As for the omission issue...he was embarrassed to tell me. Our major difference that we are trying to overcome is how we view sex/intimacy. He sees sex and intimacy as one and the same and I do not. It's getting better for us, but obviously we have a ways to go.
