Like you dudes need something more to feed your egos...but here it is anyway. No need to thank me.
Here are the results of the Lifestyles condoms cock size study, the one that announced the avg cock size is 5.7" erect (fantastic news for guys like me - I'm in the 88% range). For your comparison to be meaningful, you need to strictly measure your penis the way it was done in the study--measure along the top of your cock (not the lengthier bottom or side), pushing the ruler into the skin until it meets strong resistance by the pubic bone. I believe it's the pushing into the pubic bone that gives a higher average than the Berkeley study that had an penis length average of 5.1".
One conclusion: big cocks are a rarity. Going by the table below, out of a random population of 1,000 men, only 8 men will have cocks 8" or larger. We'll all excuse those big grins on all your faces right about now...
