There are more small penises (less than 5in) than large gigantic penises(5in +) in the human population.
What does this mean? This means that small penises are the dominant trait in the human population.
Years of evolution have allowed the penis to shrink, meaning a smaller penis is more efficient and advanced, and more adapted to today's world. Perhaps this is why most men who are successful and ahead of the group are men with small penises. I laugh at men with big penises, such underdeveloped apes!
