"What Are You Waiting For?" by Dannah Gresh

This book on--ahem--sexuality is written with a Christian perspective. The author quotes Scripture every now and then and goes over hot-button topics that most people would blush at. The cover boasts that there is something no one tells you about sex. I hate to be a spoiler, but you guys would have discovered this early in the book anyway. The author goes back to Hebrew translations of the Bible where to have intercourse with someone was called "yada" and meant to know. This is for a one-to-one relationship between a man and a wife. In the Bible, there is another term for sex outside of marriage (often with harlots) that is translated to literally just being an exchange of bodily fluids. The author also uses statistics and simple neuroscience to get her points across. The main thing that this book focuses on is that sex outside of marriage will never be the deep and intimate "yada"; it will just be an exchange of fluids that leaves you broken and sad. While the book is geared towards females, males can read it, too.
