The following interchange took place at 3 am today: "Babe, baby's crying. It's your turn." "Ugh. Can you just go instead?" "Motherfucker, I sucked your dick tonight. Get your goddamned kid." This led to a conversation this morning of the bargaining power of sex acts. Like, is head worth paying for groceries or folding the laundry? And how long is this bargaining power good for? Does anal last longer? A rim job is good for two weeks of him doing the dishes? Focus: What is the bargaining value of sex?
