I would hazard a guess that most guys will find that their girth and length are within one to two standard deviations of each other.
I randomly chose 50 guys from the PE data site and recorded their baseline stats into a spreadsheet and crunched the numbers:
Mean length (BPEL): 6.141 inches
Std dev length: 0.831 inches
Mean girth (EG): 5.076 inches
Std dev girth: 0.579 inches
Maximum length: 7.75 inches (1.936 std dev above the mean)
Minimum length: 3.75 inches (2.877 std dev below the mean)
Maximum girth: 6.75 inches (2.891 std dev above the mean)
Minimum girth: 2.8 inches (3.931 std dev below the mean)
Max. difference between std devs (girth vs. length): 2.445 fold
Mean difference between std devs (girth vs. length): 0.782 fold
Min. difference between std devs (girth vs. length): 0.038 fold
The person with the largest difference measured 4”x5”, while the several people with the smallest difference measured 6”x5”. So, my prediction holds (for this sample, anyway) that penises typically get girthier as they get longer and vice versa.
For the sample as a whole, I did a scatter plot and linear regression on the data, which shows a positive correlation between length and girth, i.e. as length increases, girth also increases. However, given that the correlation coefficient is only 0.217, this is a weak relationship.
The other interesting bit that I got from all of this analysis is that the numbers for Thunder’s Place are very similar to the LifeStyles data set.
TP mean length: 6.141 +/- 0.831 inches
LS mean length: 5.877 +/- 0.825 inches
TP mean girth: 5.076 +/- 0.579 inches
LS mean girth: 4.972 +/- 0.508 inches
I suspect that the higher mean length for Thunder’s guys is due to us ‘trying harder’ when we take our bone press measurements. We might accept a little pain when we press, unlike the participants in Cancun.
