Pornography — broadly defined as sexually explicit images — has become a sort-of wallpaper of modern lives. It is everywhere: in our books, movies, computers, video games, social media posts, music and phones.

For many years, leaders of The Church of Jesus Christ of Latter-day Saint warned members that porn was “dangerous,” “evil” and “damnable.” They taught that viewing porn was a sin. In the past decade, though, the church has suggested that repeated porn watching is an addiction, like alcohol and drugs, often requiring professional help to overcome.

Earlier this month, apostle Patrick Kearon addressed attendees at the Utah Coalition Against Pornography conference, saying he was no expert but acknowledging he did have “painful and heartbreaking personal experience with loved ones entrapped by addictions.”

Some Latter-day Saint — and other — therapists now question the addiction hypothesis.

Count Idaho psychologist Cameron Staley, author of “Confessions of an LDS Sex Researcher” and creator of the “Life After Pornography” online program, among them. On this week’s show, he discusses whether viewing porn is a compulsive behavior; why men and women watch it; how the church has improved its rhetoric on the topic; and how to help those who want to stop looking at such images.
