Average Penis Size
Here are the statistics on erect penis lengths for white college men, in quarter-inch lengths measured by The Alfred C. Kinsey Institute for Sex Research (from the point where the penis meets the body along the top to its tip). Please note that Kinsey himself had, according to some commentators, an unusual and flawed sampling technique (no, it was not measuring the distance between his lips and the subject's abdomen and adding the depth of his mouth - this is meant to be serious!), and has been alleged to be some form of sexual pervert who also used weirdly constructed experiments to reach his conclusions:
|(note: 1 inch = 2.54 cm, 0.25 inch = 0.635 cm)|
Here the same data in graphical form in inches:
And in centimetres:
So the average penis length is 6.16 inches.
The average girth is 4.84 inches.
More recent studies have produced the following results:
A sample of 60 men studied by researchers at the University of California at San Francisco determined that the average size of their erect penises was 5.1 inches long and 4.9 inches in girth. A Brazilian urologist who measured 150 men reported that the average size of their erections was 5.7 inches long and 4.7 inches in girth.

It should be noted that ethnicity except "white" does not seem to form the background of any of the studies. A generalisation is that "whites" have an average length of 6 inches, those of "chinese" extraction have 5.5 inches, and those of "black" extraction have an average of 7 inches. Averages mean just that. For everyone half an inch shorter there is someone half an inch longer. A more useful study would be the "mode" (or most common length, rather than the "mean" which is the most common average (total length in sample divided by sample size)
