When Americans think of Communism in Eastern Europe, they imagine travel restrictions, bleak landscapes of gray concrete, miserable men and women languishing in long lines to shop in empty markets and security services snooping on the private lives of citizens. While much of this was true, our collective stereotype of Communist life does not tell the whole story.

Some might remember that Eastern bloc women enjoyed many rights and privileges unknown in liberal democracies at the time, including major state investments in their education and training, their full incorporation into the labor force, generous maternity leave allowances and guaranteed free child care. But there’s one advantage that has received little attention: Women under Communism enjoyed more sexual pleasure.

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.

How to account for this facet of life behind the Iron Curtain?

Consider Ana Durcheva from Bulgaria, who was 65 when I first met her in 2011. Having lived her first 43 years under Communism, she often complained that the new free market hindered Bulgarians’ ability to develop healthy amorous relationships.
