I am 65 and get erections like I did at 20. My problem—like you’ve written, after menopause, sex changes for some women including my wife. I’ve never cheated, but I resent the fact that she has unilaterally withdrawn from sex to the point I no longer wish to try with her. And yes I am not giving up my sex life. I would never leave my wife but having half a life from now to the day I die is not an option. What can one do?
