Data obtained by the Kinsey Report between 1938-1963 found that gay men reported their penis size as about a third of inch longer than that reported by straight men. This may suggest that gay men exagerate more, but also that hormones could be a contributing factor towards penis length and sexuality.
Sex researchers Masters and Johnson found that the smallest penis in their study was 6cm when flaccid, in a man 5-ft 11-in tall; the largest penis in their study was 14cm in a man 5-ft 7-in tall.
An unusually small penis is called a micropenis, and can be due to several medical conditions, and is typically less than 2.5cm. One of Alfred Kinsey's sex research team, Wardell Pomeroy, reports that the smallest penis they recorded was 1-inch long.
The average length of the clitoris is about 16mm regularly varying between 12-20mm. Derived from the Greek word kleitoris meaning "little hill", the BBC reports that "Australian urologist, Dr Helen O'Connell, has revealed that the clitoris is shaped more like a mountain than a hill".
Guinness World Records lists Maxi Mounds as the holder of the record of the "World's Largest Augmented Breasts". Her certificate reads:
Perhaps no other record is subject to as much wishful thinking, boasting and marketing hype, as men and their penises. American Jonah Falcon (born July 29, 1970) claims to have a 13½-inch (34cm) penis when erect, 8-inch (20cm) when flaccid (DM 2012).
