I was explaining things to a 51YO guy [in real life] about TRT basics and benefits. Then I explained that his libido could be very high for a while and asked how old his wife was? He explained around the same age and fully menopausal. I explained that this could become a real problem and I don't think that he grasped the implications.
In my case, my wife is 19 years younger. So I have not had any problems.
I can see how a marriage could become very stressed when a guy cannot get his sexual needs satisfied or stressed when the act creates resentment.
