Gennifer Flowers, Passion & Betrayal, Emery Dalton, 1995, page 41:
From my copy:
The time Bill and I had together was too precious to waste talking about his wife, but when I heard some rumors floating around Little Rock, I had to speak up. He was with me at home one evening, and I cautiously told him, "There's something you need to know. I've been hearing tales around town that Hillary is having a thing with another woman." I watched his face to see his reaction, and couldn't believe it when he burst out laughing. I was stunned! I asked him what was so funny. "Honey," he said, "she's probably eaten more p---y than I have."
