He has been living with his father since his mother died a year after he married his wife Yu. I was happy, but there was one problem. It was ED and not being able to get an erection. One day when he was worried because he wanted to have a child but nothing worked, his crotch reacted when he witnessed his father massaging his wife. I've never had anything like this before... So I told my father and his wife, ``They're having sex.''
