Everyone knows that size doesn't matter. But that doesn't stop men from believing that size totally matters, goddammit. That's why a new study may be of significant interest to a lot of men. It's a compendium of 20 studies on penis size, bringing together the phalluses of over 15,000 men to paint what the study hopes is the most accurate depiction of average size to date.
The 15,521 penises involved were all aged 17 years or older, and were measured by a health professional instead of in a bathroom around 2am with a wooden ruler from grade school. All of the penises measured were neither suffering from erectile dysfunction nor the penises of men who complained of a small penis.
The big reveal was that the mean length of a flaccid penis is around 3.6 inches, while the mean length of an erect penis is 5.16 inches. In terms of girth, it's 3.7 inches flaccid and 4.6 inches when erect. However, fewer measurements were available for erect penises versus flaccid ones in the studies used.
