Sir I never indulge in a relationship and never had sex. I have feel excited sometimes when seeing a beautiful girl and allways during lovemaking with my wife. Also I got hard erection sometimes at morning after wakeup. Here I want to mansioned that I have bad habit of watching adult content online since 7-8 years. I went to gym trice in week since 2013.
