" Many women describe the feeling of having a baby come out of their vagina as taking the biggest shit of their lives. This isn’t really a metaphor. The anal cavity and vaginal canal lean on each other; they, too, are the sex which is not one. Constipation is one of pregnancy’s principal features: the growing baby literally deforms and squeezes the lower intestines, changing the shape, flow, and plausibility of one’s feces. In late pregnancy, I was amazed to find that my shit, when it would finally emerge, had been deformed into Christmas tree ornament — type balls. Then, all through my labor, I could not shit at all, as it was keenly clear to me that letting go of the shit would mean the total disintegration of my perineum, anus, and vagina, all at once. I also knew that if, or when, I could let go of the shit, the baby would probably come out. But to do so would mean falling forever, going to pieces. "
