    Hey everyone, I found this post by the user Priapologist in another PE forum, I thought it was interesting...:

    Gentlemen,

    There seems to be some confusion about the rarity of truly big (and truly small) penises, so I did a statistical analysis for everyone. I submitted some of this information in another thread yesterday, but I felt that it bore repeating and expanding. This summary is based on the LifeStyles condoms Cancun data set:

    Mean length (n=300): 5.877 inches (14.928 cm) erect (assuming bone pressed)
    Standard deviation: 0.825 inches (2.096 cm)

    My analysis:

    Lengths at each standard deviation:

    5th sd below mean: 1.752 inches
    4th sd below mean: 2.577 inches
    3rd sd below mean: 3.402 inches
    2nd sd below mean: 4.227 inches
    1st sd below mean: 5.052 inches
    Mean: 5.877 inches
    1st sd above mean: 6.702 inches
    2nd sd above mean: 7.527 inches
    3rd sd above mean: 8.352 inches
    4th sd above mean: 9.177 inches
    5th sd above mean: 10.00 inches

    Frequency in population:

    1.752 inches: 1 in 3.5 million
    2.577 inches: 1 in 31,574
    3.402 inches: 1 in 741
    4.227 inches: 1 in 44
    5.052 inches: 1 in 6
    5.877 inches: 1 in 2
    6.702 inches: 1 in 6
    7.527 inches: 1 in 44
    8.352 inches: 1 in 741
    9.177 inches: 1 in 31, 574
    10.00 inches: 1 in 3.5 million

    Rank in population, by percentile:

    1.752 inches: 0.0000003rd percentile
    2.577 inches: 0.000032nd percentile
    3.402 inches: 0.14th percentile
    4.227 inches: 2.3rd percentile
    5.052 inches: 15.9th percentile
    5.877 inches: 50th percentile
    6.702 inches: 84.1st percentile
    7.527 inches: 97.7th percentile
    8.352 inches: 99.86th percentile
    9.177 inches: 99.9968th percentile
    10.00 inches: 99.99997th percentile


    As you can see, the truly small (less than 2.5 inches) and the truly large (greater than 9 inches) are statistically very rare individuals. Given that the adult male population of the USA is approximately 105 million, there are only about 3250 guys in the entire country who are 9.2 inches long or longer, and only 30 in the entire country who possess 10 inches or more. And they are probably all in porn. See how a few dozen guys are screwing with the heads of ‘average’ length men? Making them feel small when they really, truly are not small.

    71.5 million American men fall between 5.1 and 6.7 inches, so you are in good company if you are of average length. Further, only about 17,000 American men fall into the micropenis (2.7 inches or less) category.

    Hopefully you guys find this information helpful in dispelling the ‘Monster Cock on Every Block’ myth. They really are pretty damn rare.

    Cheers!
    Pri



    NOTE: I did not do a statistical analysis on the girth data, as they were not normally distributed (they did not have a bell shape). The mean and std dev were 4.972 inches and 0.508 inches, respectively, for what it is worth

    Makes sense when you think the worlds largest "recorded" erect length is 13.5". I'm not sure the nationality or race however I heard on another site some time ago that 2 men were recorded with that length and both were in South America.

    That being said you can talk to a thousand promiscuous females and they will all state they have had the ol' 9 incher or longer :confused:

    Not to be sexist but submit this is why there are not many female contractors or carpenters out there, they would be broke from ordering way to much material :tongue: A simple 4x8 sheet of one good side plywood would look like a huge 20x14 or something :a7:

    Yes, I agree with ssa, the average length is 6 inches. 8 inches is realistic PE goal.

    This means that 8"by 6" is 99% by 97%! Also that 8.5'"by 6,5" is 99.9% by 99.9% approx!!!! I have a question for ssa the statistics master -elsewhere there has been talk of volume as the best measure of size. Most members seem to want to end up proporationate however that is not usually the case in the non PE world. The 8" guy might be 5" girth or less; the 6" girth guy might be 6" long. How common are the larger total volumes??

    Hi there pegasus. I didn't write that article but I do know about statistics. Anyway, the thing is I found the poll where the erect sizes came from and I found out that the average girth according to the poll is: 4.972 inches.
    Since the penis is not a perfect cylinder, we would need to adjust a formula, but penises come in different shapes so it would be difficult, we would also have to consider that girth is not even throughout the whole penis, so it wouldn't be right to use the same girth for every section of the penis. Anyway, if we pretended that the penis actually was a perfect cylinder, we could take an average volume so to speak.
    That would mean that the average volume, considering that the erect average is 5.877 is:

    1. First we need the radius

    Perimeter=2*PI*Radius
    =
    Radius=Perimeter/(2*PI)
    =
    Radius=Girth/(2*PI)
    =
    Radius=4.972/(2*PI)
    Radius= .7913 inches.

    Now we can calculate the average volume of a penis:

    Volume= PI*Radius(squared)*height
    Volume=PI*.7913(squared)*length
    Volume= 11.561 inches

    For a better conception:
    1 inch= 2.54 cms
    1 sq. inch= 16.387
    so now....... 11.561 * 16.387 = 189.45 sq. centimeters is the average volume

    Hi ssa. You mean cubic centimeters I take it. This of course is average volume and a worthy answer in itself -however my question is more difficult as girth and length are not closely tied. One would need to adjust for this.
    I would think volumes over 300 cu centi would be rare, for instance 8" by 6.1" woud give approx this figure(3oocu cent) if length and girth were perfectly tied that would be 99% or one in one hundred approx.
    If they were not tied at all it would be one in 100 TIMES one in 100 or one in 10,000 all very approx . Of course neither is true.
    I realise assumptions would have to be made, but this is a question worthy of a true master of stats and quite beyond me.

    Ssa take a look at how do you compare thread started by sikdog and the Mr average thing within. Cool eh. Does not answer my question though. Perhaps Uber would like a go at it ? Perhaps there is not enough info?

    Studies have shown that males (on average) are superior at spatial reasoning, while females (on average) are more verbally acute.

    I have to agree with you on this Big Al.
    Some of the male members on here are quite spaced and all of the women
    are quite cute. *Hee*
