i think if that was posted on facebook..he would be kicked off pretty quickly..unless he has his page blocked by the public..but even still i don't believe they allow any nudity on fb..but he does look to have a good size
You could get a better chance at guaging it if you got a handwidth in there. We do have a thumb width on there, so you can estimate. 99% of people will have a thumb not 1" wide, it will be more like 3/4" wide. Can guage thumb widths up and down the shaft.
Well, that keyboard in the background looks just like mine and the space bar is just about 4" long. So...as far as I can tell, Threak's rendering looks damn accurate.
