I think that an easy way to divide the cock size world up is into thirds. About 1/3 are big or above 7 inches or 6 inches and thick; about 1/3 are 5-6 inches; and about 1/3 are less than 5 inches. I think this is why "A 2005 study found only 55 percent of men were satisfied with their penis size." The 55% are the bigger group.
