I've been to Poland, and though the women there are very beautiful, I think you are incorrectly generalizing. Most of them do not have huge knockers. Though most Slavic and other east european girls (that would include Poles, Czechs, Slovaks.. and let's lump Hungarians in there too though technically they're Magyar, and Russians and Romanians, too... but not Germans) seem to have those very curvy super "feminine" bodies- thin waists, decent sized breasts, curvy hips shapely legs- that seem to be the ideal in porn (maybe in part because so much porn is shot in eastern Europe anymore), not so much in fashion where waifish is still more popular than curvy. The kind of bodies that Korean girls will punish themselves in the gym every day trying to obtain in vain because most of them simply aren't built like that.
