The situation is very difficult for me. I'd like it to be a daily event but find myself feeling fortunate if we make love once a week. He feels resigned to the situation. I have no interest in seeking sex elsewhere, yet I am so unhappy and frustrated with the way things are. Personally, I find sex a big stress reliever.
Sex works as a stress reliever for some, and goes out the window for others under stress.
It's very individual. Urge him to get a physical exam, particularly checking testosterone levels. If nothing shows up, ask him to look for another way of handling stress or maybe even consider a change of job. Be sure to say this is for your sake and the sake of your relationship rather than trying to convince him that he ought to take steps to recover his lost libido. I am a heterosexual male in my 20s in a relationship that is perfect in every way, but I have an obvious problem.
