Clinical Psychologist, Certified Sex Therapist Supervisor, Consultant and Expert Witness

Dr. David J. Ley is a world-renowned clinical psychologist, known for bringing scientifically-accurate and clinically sound information to discussions about modern sexuality.

He serves on the board of the Sexual Health Alliance as an expert advisor and is an internationally-recognized expert on issues related to sexuality, pornography and mental health.

He has appeared on television with Anderson Cooper, Katie Couric, Dr. Phil and others. He has been interviewed in publications ranging from the New York Times, Washington Post, LA Times and the London Telegraph, to Playboy and Hustler magazines. Dr. Ley has published extensively in both the academic and “pop” realms of literature. His latest book, Ethical Porn for Dicks, A Man's Guide to Responsible Viewing Pleasure has endorsements from Dan Savage and Pornhub.com and is a humorous and provocative handbook for men who want to think more comprehensively about porn.

In 2018, he spoke with Esther Perel, at her Sessions Live conference exploring The Masculinity Paradox. His talk, seen here, offers a concise overview of his view on masculinity and sexual integrity.

The Myth of Sex Addiction (2012) and Insatiable Wives (2009) were revolutionary explorations of sexual issues which blended a powerful client-centered narrative with a rich understanding of psychology, biology and sociology.

Dr. Ley is starting a new project, exploring the stories behind people who engage in professional sexual misconduct. Why do teachers, lawyers, doctors, therapists and police cross sexual lines? He is interested in conducting confidential, anonymous interviews with people who have insight into these experiences.

“David Ley’s reasonable, calm, informed writing should be read by anyone interested in porn-and it should be required reading for anyone tempted to legislate about it.”
