" I learned the rule about lesbians’ nipples from the porn books my stepfather kept under his mattress, the same place I had learned about oral sex and tribadism. The last two had fascinated and excited me even though I wasn’t completely clear on how they were accomplished. Where did the hip fit, and exactly what was the tongue supposed to be searching for? It was astonishing how badly that stuff was written. How was I supposed to figure things out when it was always so short on the important details? "
