Well interesting link. I don't know if a serious study was done or not, but I find so much of the ranking so wrong, I think this must be a leg puller. The only thing I find directionally correct is that Asia has the smallest on average.
For the rest of it (especially as it relates to Latin America....a region I am very familiar with), it is mostly laughable:
* Mexico bigger than USA. No way this is true.
* Bolivia has bigger than Brazil. Huh?? I have been to both. Simply not true.
* Chile is roughly same as Argentina? Impossible. I lived in Chile and they are renowned for being
amongst the smallest in South America......and my experience there validates that view.
* Ecuador has the second largest in the world?? I called my gay friend who had lived in Ecuador working for
Texaco for five years to tell him this. He had to hang up the phone cause he was laughing so hard.
Anyone that travels to Ecuador looking for big stuff as a result of this reports will be seriously
disappointed.
Anyway, it would be fun if a credible study of global penis sizes was available, but I don't think this is it.
