Book excerpt: We all know how amazingly accurate astrology can be about reading personalities and predicting action based on the position of the stars in relation to our own signs. But what about the most intimate (and elusive) aspect of our lives: our sexual selves. How can we be sure our partner will be compatible with our energy and needs? Can the stars help us really know? In The Complete Idiot's Guide to Sextrology, Megan Skinner, astrologist extraordinaire, tells us how to use the stars to find the perfect sexual mate. She profiles the sexual traits of each of the 12 signs, then shows us every combination of them and what to expect in bed. Funny, insightful, and practical, this helpful handbook will ensure success to anyone looking for the perfect partner.
