A comparative sociological study of East and West Germans conducted after reunification in 1990 found that Eastern women had twice as many orgasms as Western women. Researchers marveled at this disparity in reported sexual satisfaction, especially since East German women suffered from the notorious double burden of formal employment and housework. In contrast, postwar West German women had stayed home and enjoyed all the labor-saving devices produced by the roaring capitalist economy. But they had less sex, and less satisfying sex, than women who had to line up for toilet paper.
