In comparison, young unmarried women in America were fortunate: They had a certain measure of sexual freedom. Eighteenth-century parents allowed their daughters to spend tie with suitors unsupervised, and courting couples openly engaged in "bundling," the practice of sleeping together without undressing, in the girls' homes. (Theoretically, that is, they were sleeping together without undressing: in fact, premarital pregnancy boomed during the period of 1750 to 1780, when bundling was nearly universal.) But by the turn of the century, in a complete reversal of previous beliefs about women's sexuality, the idea took hold that only men were carnal creatures; women were thought to be passionless and therefore morally superior.
