I feel obliged to post the following information from time to time:

According to the largest scientific study of penis size, the mean (average) erect length was 13.12 cm (5.17 inches) with a standard deviation of 1.66 cm (0.65 inches).

What does this mean? Assuming that the sample (= 692) is representative of the population generally and that the data are distributed ”normally” (i.e., a “bell-shaped curve”),

68% of the population would be within one standard deviation of the mean [i.e., 13.12 cm (5.17 in) +/- 1.66 cm (0.65 in)] or between 11.46 and 14.78 cm (4.51 to 5.82 inches);

95% of the population would be within two standard deviations of the mean or between 9.8 and 16.44 cm (3.86 to 6.47 inches); and

99.7% of the population would be within three standard deviations of the mean or between 8.14 and 18.1 cm (3.2 to 7.13 inches).

Another way to put this is that if you take an erect penis at random (try it, it’s fun), there is a 15.87% chance of it being longer than 14.78 cm (5.82 inches), a 2.28% chance of it being longer than 16.44 cm (6.47 inches), and a 0.13% chance of it being longer than 18.1 cm (7.13 inches).

An 8 inch (20.32 cm) erect penis is 4.38 standard deviations above the mean. The probability of this occurring by chance is one in 1,464,792.

An 11 inch penis is 8.93 standard deviations above the mean. There is essentially no chance of this occurring. As a reality check, consider that the length of an erect penis that was 8.93 standard deviations below the mean would be a negative number.

The study notes that these conclusions may be affected by the relatively small number of erect penises that were measured. It is also possible that penis size is not distributed normally and may be skewed in one direction or another.

Further reading:

Am I normal? A systematic review and construction of nomograms for flaccid and erect penis length and circumference in up to 15 521 men. https://doi.org/10.1111/bju.13010

“Nomograms for flaccid pendulous [n = 10 704, mean (sd) 9.16 (1.57) cm] and stretched length [n = 14 160, mean (sd) 13.24 (1.89) cm], erect length [n = 692, mean (sd) 13.12 (1.66) cm], flaccid circumference [n = 9407, mean (sd) 9.31 (0.90) cm], and erect circumference [n = 381, mean (sd) 11.66 (1.10) cm] were constructed. Consistent and strongest significant correlation was between flaccid stretched or erect length and height, which ranged from r = 0.2 to 0.6. Limitations: relatively few erect measurements were conducted in a clinical setting and the greatest variability between studies was seen with flaccid stretched length.”

I must be lucky then.

Data I have seen suggests that 0.8% off men have a penis with a length of 8 inches or more. I have been with 2 guys that measured 7 3/4 inches before my eyes. They attested to 3 more bigger than them (one of whom I was also with). The list goes on to about 20 with a length of 7 3/4 inches or longer.

Eight inches is three standard deviations above the mean according to the Wessel's study, which is the most accurate ever done. That's about one in every six hundred and fifty men.
I guess you intentionally picked the only study with an abnormally high standard deviation and declare it the most accurate ever done because all the other data available doesn't support your agenda?

Given this post, and how all refute the notion of an 11 inch penis, and that many have talked about acquaintances with 8 inch+ cocks, I think the agenda is yours.

Despite your pompous evaluation, I don't think a single person on this site would agree from their own persons experiences that only 1 in 1.5MM persons has a penis of 8.00 inches or larger.

Just for the record on the ones I mentioned:

Pete -- College friend. I was with him when we measured his at 7 3/4". He told me his older brother's was bigger.
Jeff -- Met him a few years later. Same thing with the 7 3/4" measurement. He would always complain it was not 8 inches or over. Later, Jeff told me that his BF at the time was one of the few guys bigger him.
Andrew -- Mutual contact with Jeff. Jeff said that Andrew is at least a half inch bigger than him.
Frank -- dated not too long after I met Jeff. Longer and slightly thicker than Jeff. Since I would still have J/O and suck sessions with Jeff while still dating Frank, my observation is correct.

That is 6 that I met, just in the NYC area. I guess you have never been to New York City.

One last comment. If 1 in 1.5MM men, that implies all of them are in porn. That number is ridiculous.

I remember that Lifestyles study. My only skepticism is that is was taken at spring break in Cancun. So leads me to believe logically, the larger guys would be the ones most willing to volunteer to get measured.

But yeah even so it shows like 5% of men that were 7+ inches, if I'm reading it correctly

Are Men Getting Smaller Where It Counts?

Lifestyles average indeed is way higher than the average of all clinical conducted studies. Furthermore Ansell (the ones actually doing the study) never really released the data iirc. And there is no info at all if bp or nbp measurement.

Every study has issues. How every, Lifestyle's study was remarkably similar to my experience.

But the important fact is that even here, there are hundreds of men with actual photos proving having a penis of 8 inches.

I stand by my statement. Whatever the issues regarding Lifestyle's study, anyone with any reasonable amount of experience with men would say that only 1 in 1.5MM men have a penis greater than 8 inches is absurd.

In fact, it is so absurd a flaccid measurement would be more believable.
