I wasn't casting aspersions against Russian girls but, rather, my friend's encounters with so MANY different girls that, eventually, he would pick up an STD.
As for the Chinese, don't live with one and throw away a paper towel segment. Hold on to is and use it after it dries again later. My god, wifey yells at me for throwing away a used kleenix! (Why turn OFF the air conditioning? I don't pay electricity for the apartment!)
