When I began menstruating, the summer before I started ninth grade, my mother gave me a speech, telling me that I was to let no boy touch me, and then she asked if I knew how a woman became pregnant. I told her what I had been taught in science, about the sperm fertilizing the egg, and then she asked if I knew how, exactly, that happened. I saw the terror in her eyes and so, though I knew that aspect of procreation as well, I lied, and told her it hadn’t been explained to us.
