Also, the Asian men that were "studied" all volunteered for the study.  Hard to believe the smaller, more self-conscious guys are going to volunteer for a study like this.  Therefore the results may be a bit skewed above where they ought to be for the Asian men.

Two of the three asian men I have seen were more well endowed than almost all of the white men I have seen.

My dad is 5'6" or 5'7" tall.  I am 5'10" tall.  There was a period of years during his childhood that he was literally on the verge of starvation.  I'm guess that if he had had better nutrition growing up, he'd probably be taller.  

Aside from innate genetic differences between individuals, environment factors such as a healthy childhood probably affect the final penis size.  

Personally, I'm quite happy with my penis size (average).  If you're penis size is at least close to average, you might want to think about more important issues such as being kind to your wife and kids.  .

Out of about a dozen Asian men that I have had the pleasure of all but one were one the small side. The 'one' was a very nice average but I have yet to see an Asian man who has a 'King Kong Dong'. LOL

I believe that it's talent, not size, that gets the job done well. If size was necessary then fingers and tongues would never succeed ;o)

because the average gorilla penis is around 3.5cm when full erect.  (That's under a 1.5 ins for the metrically challenged)

Homo Sapiens have the largest average penis size of all the primates.
