A 2005 study reported that "there is no scientific background to support the alleged oversized penis in black people".A study of 253 men from Tanzania found that the average stretched flaccid penis length of Tanzanian males is 11.5 cm (4.53 inches) long, smaller than the worldwide average, stretched flaccid penis length of 13.24 cm (5.21 inches), and average erect penis length of 13.12 cm (5.17 inches).A 2016 study of 248 Korean men identified the average erect penis length to be 13.53 cm (5.33 in). A study of 115 men from Nigeria found that the average flaccid stretched penis length of Nigerian males is 13.37 cm (5.26 inches) long, which is near identical to the worldwide average, stretched flaccid penis length of 13.24 cm (5.21 inches) and average erect penis length of 13.12 cm (5.17 inches). A 2014 American study by Herbenick et al. of 1,661 sexually active men involving Asian American, Black American, White American, Pacific Islander/Hawaiian, and Native American men, found average 
racial differences in erect penile length and circumference to be generally less than one centimeter, with averages in length being: 14.14 cm (5.56 inches) for Asian Americans, 14.66 cm (5.77 inches) for Black Americans, 14.88 cm (5.85 inches) for Pacific Islanders/Hawaiians, 12.86 cm for Native Americans (5.06 inches), and 14.18 cm (5.58 inches) for White Americans (And in circumference: Asians 12.10 cm, Blacks 12.29 cm, Pacific Islanders 11.88 cm, Native Americans 11.36 cm, and Whites 12.25 cm).
Scholars believe that most ancient Greeks probably had roughly the same size penises as most other Europeans, but Greek artistic portrayals of handsome youths show them with inordinately small, uncircumcised penises with disproportionately large foreskins, indicating that these were seen as ideal. Large penises in Greek art are reserved exclusively for comically grotesque figures, such as satyrs, a class of hideous, horse-like woodland spirits, who are shown in Greek art with absurdly massive penises. Actors portraying male characters in ancient Greek comedy wore enormous, fake, red penises, which dangled underneath their costumes; these were intended as ridiculous and were meant to be laughed at.In Aristophaness comedy The Clouds, "Mr. Good Reason" gives the character Pheidippides a description of the ideal youth: "A glistening chest and glowing skin / Broad shoulders, a small tongue /A mighty bottom and a tiny prong." In Greek mythology, Priapus, the god of fertility, had an impossibly large penis that was always permanently erect. Priapus was widely seen as hideous and unattractive. A scholion on Apollonius of Rhodess Argonautica states that, when Priapuss mother Aphrodite, the goddess of love and beauty, gave birth to him, she was so horrified by the size of his penis, his massive potbelly, and his huge tongue that she abandoned him to die in the wilderness. A herdsman found him and raised him as his son, later discovering that Priapus could use his massive penis to aid in the growth of plants.Nonetheless, there are indications that the Greeks had an open mind about large penises.
