Yeah, i've no particular bias to say wich nations have easiest women, just saying what i ever seen in my life
Without counting muslim world for obvious reasons, east asian girls seems the closed/hard ones
They just go in places eat/drink shit, take some pics and that tourist stuff, but will usually seems shy even about eye contact and unwilling to interact much with locals lol
Then some are on funny side, but as far i seen rare thing (here)
We have also lot of that true-stereotypes for easy euros too, like spanish being fun af friendly party goers or super good looking eastern ones having surprising low standards, but while often true they don't compare with american girls on being easy game(as far i seen)
Only european legit competition to USA i would say are english girls that are not as wide open while sober (still friendly) but seem to have tradition of get trashy shit-drunk (specially early 20s ones) at some point of the night and from there end up being ok to be fucked by random local guy, even if he looks like shit and just had quick enough eye to see her before other players lol
Play on italian gimmick definitely helps, most of random chatting starts with shit like if they're liking Italy, what have they seen, you should see this and that as if we are fucking tour operators lol, usually followed up with talk about super normal italian stuff that somehow seems perceived as precious secret only 100% authentic italian can know, that give you world-traveler cred points lol... that or teach them words, possibly slurs lol
Then after bit drinks and fun you can be bit more direct about best way to end the night, wich is usually same shit your friends are doing with her friends, table is won and our national duty has been satisfied
