I've also seen him on cam, and yes - his dick hangs down to just one or two inches above his knee caps when he's standing. He stood up to show me on my request. He told me it's 15 inches long and 7 around. At first I thought it had to be thicker than 7 around, but thinking about it, it seems reasonable.
I have some of his pics, and I also recorded some of it (moving, low quality webcam shots). I've never posted any of his pics on the net, and I won't do it, feeling bad enough about recording him without telling him.
I've seen a few of his webcam pics around the net, so obviously somebody else posted them (the pics were called 'batman', I think). Most people will think they are fakes because of the low quality, though.
This was some years ago (4-5 years), he was sexually frustrated at that time, spent many hours jacking off on cam weekly. Hopefully he's found a woman who can satisfy him now, at least I have not seen him much online the past few years.
