It may be racist, but there are studies that show physical differences by race, including this biazrre one on the lengths of mens dicks:
Historical records of phsiology
"It is generally said that the penis of the Negro is very large," so
wrote German anthropologist Johann Friedrich Blumenbach in 1795.
"And this assertion is so far borne out by the remarkable genitory
apparatus of an Ethiopian which I have in my anatomical collection."
Louis Jacolliet, a 19th century French writer who spent three decades
investigating penis size, had this to say:
"In no branch of the human race are the male organs more developed than in the African Negro."
. . .
"Going strictly by the Kinsey data, which still remains one of the most
exhaustive studies on penis size to date, the average white male has a
penis measuring 6.2 inches long and 3.7 inches around, whereas the
average black male has a penis 6.3 by 3.8 inches."
Does Size Matter?
It’s an urban legend that women prefer men with large schlongs:
I heard a woman joke to me once saying “Once you try black you never go back!”
So, is it true that black people are well-endowed then us crackers?
I happen to know a physician who does zillions of physical exams and he says he has examined thousands of wangs over the decades and that it’s true!
There are racial differences in penis size, at least in the population of African Americans. (The doctor noted that the US sample may be skewed because British and American slaves were selected solely because of their physical characteristics.
The doctor reports that American black males do indeed have larger members, on average, about one inch longer than Caucasian guys.
The doctor also noted that males with longer member tended to have higher serum testosterone values in blood tests.
