Well, there ARE truly fat dicks with an incredible girth and I often got living proofs regarding personal encounters.
In this thread there are some photoshopped ones as well, of course, it is hard to recognize fakes nowadays because of the great technical progess; but what is more obvious to me there are many dicks which are of good size but don't show any remarkable girth at all.
So you have to decide what is more ispiring for your visual lust. A photoshop dick of unique caliber or a nice dick with mediocre size.
When a thread is titled MEN WITH REALLY THICK COCKS I do expect girth. And in that case I do prefer a good photoshopped dick more than an ordinary or average size.
