    The Wikipedia article on penis size give much smaller averages than most: this is because it confines itself to scientific studies:

    Here is the relevant part:
    ---------------------------

    There have been several studies regarding the average size of the human penis. The majority of such studies could be flawed due to self-selection bias: men with a below-average sized penis might be less likely to allow themselves to be measured, or men with a larger-than average sized penis might be more likely to allow themselves to be measured (making the figures noted below also above the true average).



    Erect length

    Regarding the length of the adult fully erect penis (measured along the top of the penis from the groin to the tip), several studies have been performed. Studies that have relied on self-measurement consistently reported a higher average than those that had staff take the measurements.
    • A study published in the September 1996 Journal of Urology concluded that average erect length was 5 inches (12.9 cm). (Measured by staff).
    • A UCSF study by Wessells et.al. published in 1996 found an average of 5.1 inches (13.0 cm). (Measured by researchers)
    • A study by a Brazilian urologist found an average of 5.7 inches (14.5 cm). (Measured by researchers)
    • A German study in 1996 also reported an average of 5.7 inches (14.5 cm). (Measured by researchers)
    • A study conducted by LifeStyles Condoms during 2001 Spring Break in CancĂșn found an average of 5.9 inches (15.0 cm). (Measured by staff)

    Erect circumference

    Similarly, regarding the circumference of the adult fully erect penis (with the measurement taken from the midshaft of the penis), several studies have been performed. Just as with length, those studies that relied on self-measurement consistently reported a higher average than those that had staff take the measurements.
    • An UCSF study by Wessells et.al. published in 1996 found an average of 4.9 inches (12.4 cm). (Measured by researchers)[4]
    • A study by a Brazilian urologist found an average of 4.7 inches (11.9 cm). (Measured by researchers)
    • A study conducted by LifeStyles Condoms during 2001 Spring Break in CancĂșn found an average of 5.0 inches (12.7 cm). (Measured by researchers)

    So maybe a lot more people are eligible to be here than you'd think.

    Most important part of the original arcticle on the Wikipedia page is the link to LPSG! Good stuff!

    I like how their 'erect circumference' bar graph seems to imply that guys with my girth don't exist.

    I have seen that before and thought it was interesting because the Kinsey study reports an average of like 6.3 or 6.4 inches or something like that. It does make sense that the actual average is smaller than that because the measurements were taken by the people being studied. Who knows though, in my opinion, a more comprehensive study needs to be done to put the issue to rest.

    The same comparisant could be made for the IQ charts that are presented on wikipedia. Visually, it would seem that IQs in the 160+ margin are vritually non existant.


    But, it's merely a representation of the rarity.

    Or someone fibbed with their marker!


    Let's pick the second.

    I'm game.
    Are you?

    Wow, you're right, it has gone missing from the external links portion of that page... odd (I know I did see it on there before as well).

    Somebody mustn't of liked letting those wondering know a site such as this exists!

    There are a variety of rules for Wikipedia (and some control freaks who like to enforce them), and one is about how many links there can be to fan sites. Maybe someone has put a link to a site they think is more authoritative than this, or some such. Wikipedia is in a constant state of flux, not all of it for the good. As someone said, it is like a restroom, only as clean as the last person who used it. For anything that isn t in dispute, it is OK, but not for anything contentious.
