A month ago I found this site https://programs.addorecovery.com/free/ which is made by dr. Kevin Skinner, the author of this book “Treating Pornography Addiction: The Essential Tools for Recovery”.
This program from addorecovery helps, a lot. Maybe you want to give it a try.
P.S. I’m not affiliated with addorecovery or dr Skinner, I’m just a guy who tries to get rid of his addictions.
