Oh my, my reputation precedes me. I am Eonwe’s aforementioned friend that had some time in Kenya. I went with a group of 21 Americans, 19 girls, 2 guys. Out of the 19 I know of three who had sex with Kenyan men.
It was interesting to me because people always talk about how “if only the African’s had access to condoms” or “if only they were educated about condoms” of course they would have safe sex and the AIDS epidemic there would be cut off at the pass. The interesting thing to note was that all three of the girls HAD condoms with them and right there in the situation. They also knew that 1/3 people (at least) in the areas we were in had AIDS but frighteningly enough, only 2 of them chose to use the condoms. Why? Because the girth of these men was so incredible that it was nearly a feat of magic to pull one on. Of course, three men is a far cry from a good scientific study and measurements were not taken 
but it made me think about how many couples in Africa just couldn’t use those condoms that were made according to European/American “averages”. Over there there is no access to the extra large variety.
I will say one thing though, man can those things stretch!
So this is maybe more of a comment on AIDS but I think that most men of European decent are somewhere near the same size but I certainly wouldn’t say that just because we are human we are all built the same.
Also, on a side note I would like to add my two cents to say that, though I wouldn’t consider myself the most experienced girl in the world, bigger is certainly not necessarily better. We German/Czech/British/Jewish girls simply were not intended to take on African men. But then that is just me. Ah…way too much information
