She is very expressive, with exaggerated facial movements. I would not say this is typical. :)) Tons of American women are still having kids, don't worry. Why do you think American women like to talk about sex? Many are still uptight about such issues...again, it is dependent on personality, not the country from which you originate. I'm sure there are plenty of females in Russia who openly talk about sex and/or their physical desires and needs.
