The (statistical) Truth About Cock Size

The (statistical) Truth About Cock Size

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!

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.

I may not be a one in a million, but I sure am a one in a 741 :) . Thanks for the analysis. Once I hit my goal, I will be 1 in 31,754! That would statistically make me the longest guy at my university. According to the current numbers, there are 14 guys with my current length at my university.

Very cool priapologist, I especially like the frequency in population.

Thanks!

Interesting. Thanks.

Funny, with the amount of members here who’s wife/gf/ex claims to have had a 10 incher, those 30 guys must really get around.

Priapologist, thanks so much for running these numbers. Very interesting.

Lifestyles Condom Co. released the results of its own more extensive and (hopefully more accurate [than Kinsey’s self measured]) study: they found the average length of an erect penis to be only 5.877 inches with most men falling in the 5.1 to 6.2 inch range. This time, measurements were taken by nurses from the point where the penis meets the body (at the pubic bone). The study also found that the average erect penis had a girth of 4.972 inches, with three quarters of dudes measuring between 4.5 and 5.5 inches around.

We’re here to grow, so it makes sense that the largest of the large would be here. When the growing gets tough, they come here.

Thanks for finding that reference sta-kool. I assumed that the LifeStyles study used BP measurement because it was conducted by clinical/medical personal and that is de rigueur with those folks. All other clinical/medical studies that I have seen, that do not use BPEL, use FSL, which is not as robust of a metric, IMHO.

Aside from the wonky girth data, one notable flaw in this study is that it is not truly random, since the semi-drunk/drunk American college students are something of a narrow field to begin with. Add to this the self-selection bias, i.e. the dudes with the highest self confidence/lowest inhibitions would likely have been the most eager to volunteer. If this high self esteem/low inhibitions was a direct consequence of being ‘hung’, then this would have shifted the mean upward. In fact, barring self-reported surveys, these data reveal the largest size, in both length and girth, of any study that I am aware of.

It is an acceptable flaw, though, since it suggests that the actual mean length and girth of US men might actually be lower than the numbers that I ran (which would make everyone even bigger, statistically). Caveat emptor? Perhaps, but I do like the explanation of one sexologist: in other studies, the men are in medical offices, there to see their doctor, and are less likely to be pulling a superstiff, even with caverject on board, whereas the Cancun guys had just been boozing it up with hotties at a night club, they’re drunk, and they’ve got two (assumedly) cute nurses measuring their cocks.

Wood, indeed.

So, I prefer to think that the numbers are more or less accurate (otherwise, I wouldn’t have done the damn thing in the first place). :)

Some women exaggerate their partner’s penis size to keep their ego up. My ex once bragged my size as 10” (actually little over 8” nbp) to two of her friends and both of them replied their husband too was 10”. I am sure if she had told them my was size 12”, the size of their husband’s penis would have been increased 12” too. I rarely believe on girls for their ex-partners penis size.

Lol, my thoughts exactly.

Yeah, I thought the same. It is not only about Thunders but also other forums where every woman seems to have had an ex which is supposed to have been “huge”.

There are 3 solutions for this:

1.These women are lying/exaggerating
2.These women have been fooled and/or have no clue how to measure a dick
3. The statistics are wrong

I am still unsure about what to believe.

Well, I wanna get huge anyways.

Isn´t it more logical that men come here because their penis is small and they want it to become larger?

Here are the stats for the Lifestyle survey :
http://www.mraverage.com/results.htm

Remember that average and median are two different things ..

Taken from the link posted above :

“The average is 5.88”, however the nature of distribution means the average is not the same as most common. This is because the few very long ones, bias things. So the median is 5.65”. That’s the point where 50% will be larger and 50% smaller. It’s the typical size.”


April 2008 : BPEL = 13.6 cm NBPEL = 12.7 cm ( measured girth wrong I think, so I won´t put it up here before next time I measure)

May 2008 : BPEL = 14.2 cm NBPEL = 12.8 cm

June 2008 : BPEL = 14.7 cm NBEL = 13 cm MSEG = 10.9 cm

Feels like you can cruise by a very large percentage of the worlds population per year if you keep the PE up.
