Not to put down the Pony, but its seems from this that the recently posted "WP walking with a flaccid" picture comparing him to Jack Napier or whatever was more like a standard downward curving erection. In the early part of that BJ scene here, he seems to start off quite a bit smaller and even that's most likely not his true starting point.
PS- Why do their porno girls look so much nicer than ours? Is it such a different class of girl that makes up the stripper/porn circuit over there, or do their viewers just have better taste and would rather look at those? Maybe someone can work out a trade with Thompson.
