[P.S. to my Link 11:]
However, Condomania (.com) claims that it has "the most comprehensive database of penis sizes on the planet," garnered (through its Theyfit measuring kit for ordering custom-sized condoms) from 27,000+ men in 76 countries, but that it "has just now begun to analyze this incredible cache of data." Apparently the only information released so far is  the rankings by size of 50 states and twenty cities (overall averages; not broken down by individuals), and  that 50% of all penises measure between 5" and 6", with 25% below 5" and 25% above 6". ~~~ Stay tuned--when/if Condomania publishes detailed charts, they will doubtless be the most definitive yet.
