So almost every Gaffer is above average.... this thread proves how (un)reliable the posters on here are!
Either straight up liars or you pressed the ruler so hard against the base of your cock that there's probably a permanent indent on there now.
Here's how the study did it.
Gentlemen, if youre eager to see how you measure up, youll need to follow the same measurement procedure used in the study. All length measurements were made from the pubic bone to the tip of the glans on the top side of the penis. Any fat covering the pubic bone was compressed before measurement, and any additional length provided by foreskin was not counted. Circumference was measured at the base of the penis or around the middle of the shaft, as the two sites were deemed equivalent.
