High Libido or Hypersexuality? The Neuroscience Behind Porn Addiction, with Dr. Trish Leigh

I sit down with Dr. Trish Leigh, a cognitive neuroscientist and neurofeedback clinician, to unpack what pornography and screen compulsions can do to the brain, from dopamine dependency and hypersexuality to sexual dysfunction and impaired self-regulation. We explore why so many men struggle to break the habit, how pornography can become a tool for managing stress and boredom, and why simply trying to quit often isn't enough.

Dr. Leigh explains how the brain can be rewired through repetition, healthier sources of dopamine, intentional routines, and what she calls the “instant rewire.” We also talk about shame, relationships, parenting, ADHD symptoms, and how rebuilding a healthier brain can help men create the life and relationships they actually want.
