I am not aware of any systematic attempt to determine the world's longest male member, however specimens as long as 13 inches (when erect) and as short as 3 inches have been reported.
When you get to talking about averages, though, it's another story. The famous sex research pioneer Alfred C. Kinsey kept track of all kinds of weird stuff when he was doing his surveys. Penis length (and girth) were among the things he studied.
The results are recorded in a fascinating volume called The Kinsey Data (Gebhard and Johnson, editors, 1979). This includes tables on topics like "Which Testicle Lower in Scrotum," "Incidence of Playing Strip Poker," and "Extent of Sexual Contact with Animals." (Like I say, the doc was a mighty curious guy.)
Kinsey's data indicate there's a lot more variation in flaccid penis length than there is in erect penis length. Under actual working conditions, in other words, things tend to even out.
The most striking demonstration of this is the comparison between whites and blacks.
Largely on the basis of furtive observations in the locker room, white males tend to believe that blacks are better endowed than they are. Kinsey's measurements of flaccid penis length tend to bear this out.
White males had an average flaccid penis length of 4.0 inches, whereas the average black male's detumescent member measured 4.3 inches. But when erect, the average white penis was 6.2 inches long, whereas the average black's was 6.3 inches--still longer, but not by much. (Average circumference for whites was 3.7 inches; for blacks, 3.8.)
These figures must be regarded with caution. There were more than 2,500 white male respondents, but only 59 black males.
(Incidentally, for those who wish to pursue this matter on their own, you measure along the top. You'd be amazed how often this question comes up.)
Kinsey is silent regarding Oriental endowments. But we have evidence from other quarters--columnist Bob Greene, of all people.
In his book Cheeseburgers, Greene reports that during a visit to the Trojan prophylactic factory he learned that condoms come in two sizes--7.1 inches by 52 millimeters for the American market, 6.3 inches by 49 millimeters for Japan.
A comforting thought. The Japanese may be smarter and better organized, but there's one place where we've still got 'em beat.
