Well when I said the lack of intimacy was mutual, I don't mean we ever discussed it, just that both of us were angry at each other a lot so sex became infrequent. Then I was badly injured, and my recovery was worsened by bull-headedness on my part being unwilling at first to accept the gravity of the situation so my wife stopped seeing me as a strong male and piled a lot of blame on me for the situation as well. I should note that while I was no longer the bull of the man I was before my injury, I still worked and provided for the family and spent time doing things with my son to the best of my ability and still do to this day.
For years between my injury and problems related to it and my wife's anger with me for being somewhat culpable for worsening my injury when it first happened, I accepted with the lack of intimacy, but eventually I recovered to the point that my sex drive has been getting stronger and stronger and the lack of intimacy has been much more palpable for me.
As far as the prostitutes, they were before I was married to my wife or before I even met her. When the situation came about where I found out my wife was so anti-prostitute and she ended up asking me whether I had been with prostitutes, I had not expected her negative viewpoint about prostitutes and it was quite clear it would be a big deal. At that point we had a young child together and we argued about so many things already I didn't think her narrow view of something I had done in the past before I met her was something I had to be accountable to her about. I don't view prostitutes or sex-work as immoral and despite what people say, it doesn't have to be a degrading situation for either yourself or the prostitute and it wasn't for me.
So now I am 18 years into my marriage and despite her anger she didn't leave and I don't think she will at least until my son graduates high-school in about a year. She has told me point blank she prefers divorce to counseling, but still I have doubts she will initiate a divorce even then unless things were to become intolerable to her.
So it is left to me to decide what I can tolerate.
