1) the mean erect penis length was 5.3 in. (13.5 cm)
2) with 68% of men measuring between 4.6 and 6.0 in. (11.7 cm and 15.2 cm)
3) 13.5% between 6.1 and 6.8 in. (15.5 cm and 17.3 cm)
4) only about 2.5% of men possessed a penis over 6.9 in. (17.5 cm) long
In other words if your penis was 6.9 inches and you were in a room of 100 randomly chosen men only 2 and a half penises (okay, okay 3) would be larger than yours.
The link is the most authoritative paper I can find and makes the most sense.
