An old friend of mine told me about her favorite sexual position. Since I tried it with my wife, I can't stop thinking of her. Being a rear entry position, it makes it easier for me to think of her since I don't see my wife's face as I do it. Once, I even pronounced her name in the middle of an orgasm. From then on, my wife calls me her ex-boyfriend’s names as we make love. It is exciting to know she thinks of her previous sexual experiences as she makes love to me.
