Justin J. Lehmiller, a leading expert on human sexuality and author of the popular blog Sex and Psychology, has made it his career's ambition to answer these questions.

Based on his monumental two-year study of sexual fantasies involving more than 4,000 people from all walks of life, Tell Me What You Want offers an unprecedented look into our fantasy worlds and what they reveal about us. It will help you to understand your own sexual desires and how to attain them within your relationships, but also to appreciate why your partner may have sexual proclivities that are so different from your own.

Appreciating the incredible diversity of human sexual desire and why this diversity exists in the first place can help you to overcome distress, anxiety and shame about your own sexual fantasies; ultimately enhancing your sex life. Breaking down barriers to discussing sexual fantasies and allowing them to become a part your sexual reality is the pathway to maintaining more satisfying relationships.
