I'm surprised there no one has been able to claim it.

I'm about 7.8-8 inches NBP and 8.2-8.4 BP and I've always hoped I could extend or stretch and one day be 9 but surely there are guys bigger than me who could extend from 9 or a bit above 9 and get to 10?

I only have measuring tape so I need to go out and buy a ruler, I'm also at work, it's currently the middle of the day here.

Bro if your dick is 10 inches non bone pressed just started throwing pictures up next to whatever you find thats nearby. I doubt anyone is going to believe just one single picture anyways. Has to be a series of consistent pictures in a short time frame.

I will share my gift with all of you, when I'm home,I'm not taking dick pics in the work bathroom.

Someone on reddit simulated the dicksize of the whole adult male population (~ 2.6 Billion men).

He used the calcsd Western dataset, which doesn't even include East and South Asian data.

2.6 BILLION dicks simulated! : bigdickproblems

The world's adult male population is around 2.6 billion ... so a simulation for this population had to be run!

Key results : There are 12 guys with 10+" dicks in this simulated world! The longest guy is 10.27" long. The maximum girth seen was 8.55". Only one guy is over 8" girth. The biggest volume seen is a startling 25 US fl oz.

This used the calcsd Western dataset Mean and SD to create random lengths.

A mean girth was calculated for each individual length ... based on a girth-length correlation that I evaluated a while back.

The girth was then randomized using a first order len-girth-SD relation that I have obtained from a dataset I have.

Note: Recently I have been using an interesting 2nd order equation for this len-girth-SD relationship ... but this massive run revealed that the 2nd degree version was insufficiently valid at the far extremes to be reliable. I therefore switched to a more boring 1st order equation. This leads to fewer very girthy guys at huge dick lengths. I will revisit this at a later date.

(These results make me wonder about the frequency of big flairs on this sub.)

UPDATE #1:

  1. The calcsd Western dataset length & girth means etc are: 5.67" (SD 0.75") x 4.64" (SD 0.58") BPEL

  2. You can find your own volume details from the calcsd site.

  3. My volume calculation is not the same as the calcsd version ... but the results are surprisingly close.

  4. calcsd is at calcSD - Full Penis Size Percentile Calculator ..... use the Western dataset

  5. I used my new laptop to run the simulation. I was amazed that each run only takes about 15 minutes. It would take HOURS on any of my many old desktops. That laptop performance makes me realize that AI runs might be possible on a modern PC even without a GPU.
UPDATE #2

  1. It would seem that a length of 7.5"+ and/or girth of 6.0"+ and/or a volume of 9+ US fl oz indicate an unconditionally big dick.

  2. The most interesting zone is the 7.0"-7.5" and 7.5"-8.0" length area. This is the area which influence anecdotal reports of dick sizes most.

  3. From my observations over the last months I would suggest that the 6.0"-7.0" zone is where many guy seek validation that they are indeed HUGE.

  4. I have noted elsewhere that lengths below 6.8" are not necessarily visibly big.

  5. Lengths over 9" are VERY rare. Girths over 7" are VERY rare. Consider that when you review flairs.

So based on this, max. 12 people have 10 - 10.5 inches. Probably even less, since this didn't include Asian studies and the Asian population is massive compared to the rest of the world. So my guess would be about 5 men on earth have 10 inches, so good luck finding them here! :joy:
I mean I wonder how he calculated those roughly 12 people since so many SD's above the average in a normal distribution doesn't even get calculated anymore by any statistician since it makes no sense and is like 1% reliable.

I agree, the Gaussian distribution is a well defined curve, but models estimating percentiles are approximate, and become unreliable at extreme values. Robert Wadlow stood at 8' 11", which would be about 12 standard deviations above the mean. A calculation based on the normal distribution would indicate the probability of such a height existing in any person would be close to zero. The normal distribution didn't account for his pituitary tumor.

Boy, you must work some crazy long hours...

I'm not saying that I'm doubting you, but I'm probably doubting you.

Hypothetically if someone is genuinely 10 inches long npel and they don’t want their photos all over the internet forever. And they Skype you and measure they penis in front of you. Would you pay them still?
Hypothetically, yes.

However if I'm only in this to "steal" pictures of 10" to spread them all over the internet, a Skype session would be just as easy to post all over the internet than a picture or two. So I can't really see what's gained by doing Skype over pictures. Also a Skype-session might still not be conclusive and thus require a meet-n-greet.

The offer has been there all along just to message me proof in private. This is still an option but will probably make step 2 and 3 of the process harsher as I have to be certain.

What erect girth size and flaccid length size is just as rare as a 10inch erect length
I think a legit 7" 100% soft dick would be really rare. But it would also be nigh impossible to tell if the guy is indeed soft... I mean, with a few tricks you can make your "soft" length appear to be bigger than the erect length, lol.

Interestingly modern medical care is so extensive that people with those tumours are found and treated before reaching such heights, meaning Wadlow will remain the tallest human ever.

Well it says in the post: ADULT male population. No underage persons are included in this study, wouldnßt make any sense.

The data set is explained here: calcSD - The calcSD Global Average (v4)

It includes 54 studies about penis size in the whole world. Also it says the following:

Additionally, to make this average more representative of the general adult population, we have excluded:
  • Many nonrandom samples with potential size biases (such as those gathering individuals complaining of small penis)
  • Samples with appreciable proportions of underaged/undeveloped individuals
  • Studies that do not provide mean, SD, and adequate sample size
  • Data from incompatible measuring techniques
  • Data that is self-reported or otherwise unreliable
So the 54 studies are all not self-reported.

That does not account for the discrepancy. One third of males are not under 18 years old.

I appreciate the additional information, but it doesn't answer all of the questions. For example, incompatible measuring techniques isn't that meaningful. It describes neither how the measurements were done nor what they consideration were made to determine that techniques were incompatible.

Also, bullet point 2 contradicts the idea that the survey only included adults.

Bullet 3 doesn't really mean much either unless you know what population size they are trying to make a determination about. While they might have sample sizes sufficient for a smaller population, they do not have a sample large enough to represent the entire adult male population.

Someone consolidated the results from several surveys and is extrapolating information about a larger population than any of the surveys were intended for and posted it on a website. I don't expect these values to be very accurate and I think it is almost certainly too generous even if the number of men over 10 inches is very low. You already said the same thing.
