One study, the Kinsey Report, is a constantly updated and rigorously researched report that contains information on the average penis size. This report has revealed that the Ultra X Prime average white male penis size is 6.2inches long and is 6.3 inches long and 3.8 inches in circumference. That is only a couple millimeter difference, which is not significant statistically or sexually. In conclusion the Kinsey Report suggests that there is not noticeable difference in penis sizes throughout different countries or races, and on average the penis size worldwide is about 6 inches.
