Well, if it helps...
I'm 6'4", 190
Big Hand
Size 13.5 shoe (US)
8.5" x 6-6.25"
Well, since we don't have any data, we may as well compile our own. And here's a quite funny one:
Compared to the above poster, I'm shorter (5' 11" and with likely smaller hands and 1.5 shoe size smaller) but longer AND thinner as far as the penis goes. Which, by all logic of body types of all kinds relating to penis types, it is completely reverse.
By a logical correlation, I would be shorter and thicker, the exact opposite of reality. This is only one sample, but I know that if you took everyone on this site, and furthermore everyone in the world, the odds eventually favor no correlations whatsoever and would appear to be a random walk.

To go back possibly and think about this a little bit scientifically again. There is no reason, through evolution or otherwise that a large penis is essential to survival in humans. So, that is most likely why there is no trend or sense to the range of sizes and people who have them. Most of human courtship is through mental and physical means unrelated to the penis, or often in ancient times more through social standards and procedures, therefore people tend not to mate based on penis size as a factor. This means that men of all sizes are equally likely to reproduce, thus providing no gateway for men of a certain extreme size to be dominant statistically. What naturally occurs is a normal distribution with many mid-sized penises and gradually fewer and fewer as you go to the extremes of small and large.
What is ironic however, is that supposing that one size did come preferred at some point in history and lasted so for a very very long time... the average would become large or small (whichever was desirable), but a small and a large would still exist. So it is impossible to avoid always having little, average, and big, no matter how it works out.
(technically there could be a sole penis size, if only people of say precisely 5.78923 inches were allowed to reproduce, but this would take forever as even if only men of that size reproduced, because the genes of the women may still take effect. So, it would take many generations to weed out those newborn men that didn't come out the exact size by not allowing them to reproduce, but eventually it could happen. So, if anyone wants to run with this and write another 1984 or some kind of erotic story based on futuristic overcontrolled computer-worlds, there's your material :biggrin1: )
