Sisters Are Doing It For Themselves

'the body of a female masturbator might even create its own offspring, independent of human action. Physician G. A. Douglas argued in his book, The Nature and Causes of Impotence in Men, and Barrenness in Women (1758), that false conceptions could be caused by self-abuse. He suggested that women needed vaginal stimulation in order to make an egg descend. If a woman used “those shameful implements” to stimulate herself, she would produce an egg that would remain unfertilised and grow so that it resembled a pregnancy. Women, he warned, “should know this and tremble”.'
