Human Sexuality, 4th edition

Choice: Help students learn how to make their own informed decisions Packed with content that is relevant and meaningful, Human Sexuality offers the information students need to make the right choices and decisions in their own lives.

• Since You Asked features at the beginning of each chapter present a list of student questions gathered from author Roger Hock’s human sexuality classes. Each question is referenced to a page number in the chapter where the answer and discussion of the issue may be found.
• Focus on Your Feelings features early in each chapter alert students to the fact that unexpected emotions and/or reactions to provocative topics – such as sexual violence, sexually transmitted infections, and pornography – are normal and expected. This feature reassures each student that these feelings are normal, and that she is not the only one feeling them.
• Self-Discovery features offer each student opportunities to learn about herself as a unique sexual person. The Self-Discoveries may contain information to help students become better informed about their sexual bodies, or better understand their relationships with others, or appreciate the rich variations of human sexuality.
• Your Sexual Philosophy features offer students opportunities to develop their own personal sexual philosophies by considering how the material in each chapter may relate to their own lives. 
• A running theme throughout the book is that sex is far more than heterosexual intercourse. This idea, indicated by a small symbol and reminder box in nearly every chapter, is intended to remind students that a wide range of sexual activities in addition to, or instead of, intercourse can offer sexual intimacy and satisfaction without engaging in risky or unwanted behaviors.

Awareness: Boost student awareness of health, and of the diversity of the sexual world
Learning to respect and appreciate the fascinating range of human diversity enhances students’ understanding of the complex sexual world around us, and how and where we each fit into it.

• In Touch with Your Sexual Health features increase student awareness of sexual health issues. These features discuss topics such as sexual infections and diseases, problems in the functioning of the sexual body, or sexual issues that may cause psychological difficulties or emotional pain.
• Sexuality and Culture features focus on topics from diverse cultural practices and customs, highlighting the fact that the world of human sexuality is rich in cultural, subcultural, and ethnic diversity.

Responsibility: Foster the knowledge students need to lead an informed and ethical life Human Sexuality provides students with the skills to evaluate the vast amount of sexual information they receive from the media, from friends and acquaintances, and from their families.

• Sexuality, Ethics, and the Law features boost awareness of issues of ethics and the law, which are often an important part of discussions of sexuality. Examples of some issues discussed include the ethics of informing potential intimate partners about sexually transmitted infections, the ethical consideration of sex-preselection in childbirth, Megan’s Law and sex offenders, and the crime of child pornography.
• Historical Perspectives features highlight significant people or events, and provide key information about the history of the study of human sexuality.
• Evaluating Sexual Research features shed some light on how students can critically analyze sexual stories and research they may come across in newspapers, magazines, online, or on TV. These features help students become more skilled consumers of sexual research findings by learning to evaluate sexual research before accepting what that see or read as fact.
• Have You Considered? questions at the end of each chapter help students understand the material in the chapter, and encourage students to consider and analyze what they’ve learned, what the information means to them personally, and how it can be applied their own lives.
