I was getting a manicure the first time I learned that not all wives want to, ahem, go for a roll in the hay with their husbands. I was 16 and had picked out orange nail polish (oh, sixteen). I had a book with me but it wasn't long before I found another source of entertainment. In-between buffings and polishings, the two women next to me talked about how much their husbands wanted IT and how little they wanted to give IT.
