Great point. I would go further and say that the chemicals, hormones, pesticide, industrial seed oils, highly processed grains, the exorbitant amount of processed sugar, and horrible lack of nutrients in the typical western diet have lead to overall poorer health. Then add in the pollution, the medications, the addictive substances (nicotine, alcohol, etc), the stress, & the lack of sleep. We are fatter than ever, we are sicker than ever, and that impacts all parts of our bodies.
(Late 1999): 6" BPEL x 5.25" MSEG
(Early 2001): 7" BPEL x 5.75"MSEG (mostly Hanging/Jelqing)
Aug 16th 2015: 7.375" BPEL x 6" MSEG
Goal: I have retired from PE  So my goal is just maintaining.

Actually scientific study showed that human size (high, mass, bone density) drastically dropped around 10,000 years ago with the advent of agriculture, and it wasn’t until the last 100 years that we have reached the same size as our preagricultural ancestors (largely because of the over abundance of food). I wonder if Fred Flintstone had a huge member??

Here you go, this is one of the chemical affect on human penis size that skew the penis size data.

Loss of EQ can happen, but its also been shown that size doesn't actually drop, so either the average of penises are getting bigger, or the study size is not as representative of the population as we constantly try and make it sound.
Also, most theories that revolve around the evolution of penis size do not have to do with female pleasure. Most theories state the human penis evolved the way it did for other reasons.Last edited by CaptainJohnson; 11162012 at 04:05 PM.

This is a pretty popular subject, and i'm sure many people wonder where they fall in the broad scheme of things.
I knocked up a quick calculation program that will give you some statistics on your length and girth.
You can find it here:
Donjelqer76's Percentile and Frequency calculator
While not perfect, it really is statistically quite accurate given the published numbers we have to work with.
Also, to be transparent (and for peerreview), I will paste the code used to generate the page below (a little ugly, but I'm short on time). If anyone spots an error or other mathematical problem with it, please point it out.
Code:<? // Percentile and frequency calculator // (c)2012 Donjelqer76 // donjelqer76@petoolbox.com $action = isset($_REQUEST['action'])?$_REQUEST['action']:'form'; if($action!='form') { // Variables used for calculations // variables $mean_girth=4.9; // Statistical mean for girth $std_girth=0.508; // standard deviation for girth $mean_length=5.7; //statistical mean for length $std_length=0.825; // standard deviation for length $z=0.0; // Zscore $m=4.9; // Statistical Mean $s=0.508; // Statistical Standard Deviation $p=0.00; // percentile $r=0.00; // rank $frequency=0; // Frequency $pop=105000000; // Pupulation for calculation $message=""; // Message to display at the top of the page. if($_POST["length"]) { $message.="<b>Length Report:</b><br />"; // Calculate Zscore $z=ZScore($_POST["length"],$mean_length,$std_length); $message.="Your length is $z standard deviations away from the statistical mean.<br />"; // Calculate percentile $p=cdf($z); $percentile=$p*100; $message.="This puts your length in the $percentile percentile.<br />"; // Calculate rank $r=$pop * $p; // Calculate Frequency if($r > $pop/2) { $rarity=round($pop/(($pop/2)  ($r  ($pop/2)))); $message.="There are about 1 in $rarity men with a longer length than you.<br />"; } else { $rarity=round($pop/$r); $message.="There are about 1 in $rarity men with a shorter length than you.<br />"; } $message.="<br /><br />"; } if($_POST["girth"]){ $message.="<b>Girth Report:</b><br />"; // Calculate Zscore $z=ZScore($_POST["girth"],$mean_girth,$std_girth); $message.="Your girth is $z standard deviations away from the statistical mean.<br />"; // Calculate percentile $p=cdf($z); $percentile=$p*100; $message.="This puts your girth in the $percentile percentile.<br />"; // Calculate rank $r=$pop * $p; // Calculate Frequency if($r > $pop/2) { $rarity=round($pop/(($pop/2)  ($r  ($pop/2)))); $message.="There are about 1 in $rarity men with more girth than you.<br />"; } else { $rarity=round($pop/$r); $message.="There are about 1 in $rarity men with less girth than you.<br />"; } $message.="<br /><br />"; } } else { $message="Welcome to Donjelqer76's PE calculator.<br />"; $message.="The calculations here will allow you to get an estimate of "; $message.="where you stand amongst the population for both penile length, and girth.<br />"; $message.="Please enter your length and girth blow (in inches), then click on the submit button. <br /><br/>"; } ?> <!DOCTYPE html PUBLIC "//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Donjelqer76's Percentile and Frequency calculator</title> </head> <body> <? echo($message);?> <form name="compute" method="post" action="index.php"> <input type="hidden" name="action" value="compute" /> <table border="0"> <tr bgcolor="#CCCCCC"> <td> </td> <td><b>Measurement</b></td> <td><b>Units</b></td> </tr> <tr> <td><b>Length</b></td> <td><input type="text" name="length" maxlength="10" size="20" /></td> <td>(inches)</td> </tr> <tr> <td><b>Girth</b></td> <td><input type="text" name="girth" maxlength="10" size="20" /></td> <td>(inches)</td> </tr> <tr align="center"> <td colspan="3"><input type="submit" value="Submit"></td> </tr> </table> </form> </body> </html> <? // Functions for calculation function ZScore($value,$mean,$std){ return ($value$mean) / $std; } function erf($x) { $pi = 3.1415927; $a = (8*($pi  3))/(3*$pi*(4  $pi)); $x2 = $x * $x; $ax2 = $a * $x2; $num = (4/$pi) + $ax2; $denom = 1 + $ax2; $inner = ($x2)*$num/$denom; $erf2 = 1  exp($inner); return sqrt($erf2); } function cdf($n) { if($n < 0) { return (1  erf($n / sqrt(2)))/2; } else { return (1 + erf($n / sqrt(2)))/2; } } ?>
