I would think that per capita, the folks that live in Prague (I admit that I don't really know without looking whether Prague is City or a Country)(I'm just glad I can spell it)...aren't tops on that list. All the sex parties you see on red tube and tube8 and thehun are in discos in Prague, it seems. horny fuckers over there.
ahhh......googled it...Czech Republic....so they ARE on the list at least. I feel better.
prague sex tour, anyone?
