““University of Otago social historian Hera Cook provides a beautiful illustration of exactly this point in her rich account of the sexual revolution.49 Cook notes that in eighteenth-century England, women were assumed to be sexually passionate. But drawing on economic and social changes, fertility-rate patterns, personal accounts, and sex surveys and manuals, Cook charts the path toward the sexual repression of the Victorian era. This was a time of reduced female economic power, thanks to a shift from production in the home to wage earning, and there was less community pressure on men to financially support children fathered out of wedlock. And so, in the absence of well-known, reliable birth control techniques, “women could not afford to enjoy sex. The risk made it too expensive a pleasure.”50””
