I understand why some men get to the point where it's just not worth the effort. I really never knew this about myself; I had just accepted my sexless marriage as a product of its duration (40 years) but now that it is about over, I realize that I have not really lost my desire for sex, it had simply been dormant and I find I am overjoyed to find it reawakening. Every single time the guy has been resistant to talking about it and refused to do anything about it at all.
BTW, the pills don't always work or aren't recommended for some men.
I assumed he was talking about his head or his heart and tried to figure it out by asking questions, but he didn’t give any real answers, just excuses.
