Book excerpt: Dear G-Spot is New York Times bestselling author Zane's long-awaited guide to what she knows better than anyone else: love and sex. Dear G-Spot includes real letters from real people, both women and men, who have sought Zane's advice over the years -- the preacher's wife worrying about being judged, the virgin, the guy next door, the gay man next door, the woman with low self-esteem, and the other woman with a sex drive over the moon. In her own uniquely can-did and humorous way, Zane answers all your questions -- even questions you never thought to ask -- about making whoopee.
