This book is very useful for couples going into marriage as virgins. as christians abstaining till marriage, it would be a shame to have a bum honeymoon because of inexperience and lack of knowledge. this book helps. it treats sex on the levels of physical, mental, spiritual -- speaks of things that affect (for better or worse) a sexual relationship. however, this book goes beyond "newbie" level, and speaks of things that anybody may be missing from their relationship, keeping it from running smoothly. this book is written from a christian perspective, and by both a man and his wife, so you get both perspectives.
