I remember when I was about 14 my mother had bought me a pair of pants which I tried on in front of her and dad. I was wearing a pair of those short Jockey briefs. My dad said quite loudly " My God Nat he's hung like a horse!" I remember being acutely embarassed at the time and then realised that I had something that my dad didn't.( I once saw him naked as I walked into their bedroom , and I have to say 'A button on a fur coat' - comes to mind.)
