Clearly, this guy is real, whether or not his name is David Caputo, and he is hung.
The only question is, are some of the photos of him circulating on the net photoshopped to make his dick even bigger. The answer is definitely, yes.
If you look at the Yahoo group dedicated to Caputo, there are quite a few albums taken by a photographer called Charlotte York. Look in particular at
http://ph.groups.yahoo.com/group/dav...os/browse/39a5. There are some shots there of Caputo with a hard on. They look pretty natural. I don't think they are photoshopped.
He looks big in these shots -- my guess is 8 or 9 inches -- but he is not megahung the way some of the other shots floating around make him look.
