The changes that occur to preteens can be very traumatic. This book, the third in the Learning About Sex series for boys, explains to 10- to 12-year-olds that these changes are normal and are a part of God's unfolding plan for their growth and development. From preschoolers to adults, the updated and revised Learning About Sex series makes the awesome gift of sexuality understandable to all. Age-appropriate language and graphics throughout the six books help the reader recognize gender differences as one of God's great gifts designed as part of His creation plan.
