I married my wife Yu a year ago, and since my mother passed away, I've been living with my father. I was happy, but I had one problem. I couldn't get an erection because of erectile dysfunction. I wanted to have a child, so I tried a lot of things, but nothing worked. One day, I was worried because I saw my father massaging my wife, and my crotch reacted. I'd never had anything like this before... So I asked my father and wife, "Can you show me how you two have sex?"
