Resources and support groups for recovery from porn / masturbation / sex / love addiction:
For me, joining a recovery group at a sex addiction clinic in my city made a huge difference. I could speak with other men who had been through the same thing. We learned how to understand and manage our addiction, and how to live healthy, happy, sober lives.
You are definitely not alone. There are many other people, both men and women, recovering from this. And recovery is possible.
