I am 39 years old, of 5ft 11in height and weight 72kgh. I am healthy and like going to gym. My problem is that I am not turned on my wife. Previously this never happened and we has sex twice or thrice a day. Now I don, t get erect even after she touches my organ. In the gym though, if I see a hot women working out, my penis gets hard immediately. I don, t want to has sex with any one but my wife. How do I solve the problem.
