Yet another size survey

Really just a collection of other studies. I’m thrilled with the Australian girth measurements. Thank god for pump n clamp. Enjoy


Country Length (cm) Circumference (cm)
Nigeria (Gerofi) 17.0 13.4
US African (Kinsey) 16.6 12.5
US Caucasian (Kinsey) 15.8 12.3
Australia (Smith et al) 15.7 13.2
Brazil (De Ros et all) 14.5 11.9
Thailand (Muangman) 13.5 11.2
Korea (Han et all) 12.7 11.3

The “Itallion Stallion” isn’t ranked?
