Many men are self-conscious about their penis size. Odds are they don’t need to be, but now there’s a chart of what’s “normal,” just in case.
The average flaccid penis was 3.58 inches long (about 9 cm) and 3.66 inches in girth, while the average erect penis was 5.16 inches long (about 13 cm) and 4.59 inches in circumference (about 11.7 cm), according to results online March 2 in BJU International. Stretched flaccid length was often very similar to erect length
