If you really want to post a picture of your tallywhacker Godders then you go for it young man. Talking of which I'm guessing a man of your cultural calibre has seen the motion picture 'Superbad', the gallery of knob drawings at the end of that very nearly made me shit a lung with laughter. Seriously though, if you can keep your hands of yours long enough, do a wee sketch and post it, and we'll all give you our considered opinions.
PS. I'm not serious.
