Missionary position was, as far as she could tell, like vanilla ice cream: purported to be boring and chosen only by passionless, unimaginative, exhausted people but really the best one. She liked to look at Penn’s face so close that it split into pieces like a modernist painting. She liked the length of his front pressed against the length of hers. She felt that people who needed to do it upside down and backward from behind – or who added candied bacon or smoked sea salt or pieces of raw cookies to their ice cream – were probably compensating for a product that was inferior to begin with.
