There's also something that must be incorporated into consideration here (that even the "empirical statistics" seem to leave out): how tall are these guys in your samples? (fournineteenfiftynine, as you have quite a nice-looking list of guys right there, perhaps this question would apply especially to you.)
See, I have a medium-small dick at 5 inches. (I'm merely here as a supporter. lol!) But, I'm a pretty small guy barely bigger than 5 ft. 3'. Now, a guy who I know is 6 feet has about a 7(.5) inch dick, but guess what? From a spatial perspective, his dick looked pretty scaled to size. In other words, if I were his size, my dick would be around half an inch shorter or longer, if not almost exactly his size in length and girth.
