well...I am aware that Sicily is part of Italy. but there is the fact that Sicily has been populated (and conquered) over the years by the Greeks, Phoenicians, Carthiginians, Moors, Normans, Romans, and now is part of Italy..so the genetic makeup can be very different from mainland Italy.
and the Italian in me is part Sicilian and part Abbruzzi.

as for the study..well...I am aware that there is no one ethnic group that has the claim on big cocks. I am stating all the above with that in mind. I take this whole thread in a non scientific way and am just having fun with it too. but like I said..I do enjoy thinking Italians are hung the best! and that study was of men before age 19. a lot can happen after that age. and the ones I saw were all in their 30s and 40s..maybe some late 20s
