Here we go again! I am a Mexican, but my ethnic background is huge (italian, spanish, french, arab, american native (aztec), irish) and most of mexicans are the same way, maybe a little less mixed, only indian - spanish, I have seen naked and hard most of my friends and we are all different (duh!), lenght and girth and color wise, there are different races in this country,whites, latin-mixed, indians,etc.
I think we are more mixed than people in other countries, all of latin-american countries have different back-grounds, let´s see, Argentina (italian, german, spanish), Brazil (german, african, latin, portuguese) and the list goes on and on, so, conclusion, there's no conclusion when it comes to dick size. I have seen some huge ones and some that are really hard to believe how small they are, but then again, most of men at least in Mexico are average (6 inches long, 5 inches thick). | 
"Leave the lube behind, guys. Cuz if it ain't spit, it ain't love"
So, I guess the answer is the same for anywhere
