It seems to me that studies with better methodologies find smaller mean sizes; studies with poor methodologies (like the mail in cards mentioned earlier) find larger averages. Given the obvious motivation to lie and the obvious bias in sizes of observed dicks (guys with bigger dicks are more likely to show ‘em off or work in porn), it seems pretty clear that the picture we get in our daily lives of “average” is pretty damn skewed to the big side of the spectrum. Honestly, I would be shocked if the average BPEL was even close to 6.5”; I think all the numbers point to an average of around 6” or less. Also, keep in mind that these numbers are means (arithmetic averages), not medians. Means are heavily influenced by outliers (unusual observations); medians are not. So, Bohm, we have no idea what size 50% of men fall below. If the distribution is perfectly normal, then the mean and median will be the same; but this distribution is probably right-skewed, so the median would actually be less than the mean: it could be that 50% of men are 5” or below. Also, keep in mind that, given the obesity problem in the much of the world today (especially the US), mean NBPEL is going to be pretty small. I really would not be at all surprised if I heard that the median NBPEL were 5” or less in the US.
Starting (May 2010): BPEL:6" EG: 4 7/8". Current (April 2011): BPEL: 6 3/4" EG: 5 1/4".
Short Term Goal: BPEL: 7" EG: 5.25" Long Term Goal: When my wife makes me stop or 8"x6" (whichever comes first)
