Porn addiction is a way in which your brain seeks to create more dopamine because depression greatly reduces this pleasure hormone. It is another means of escape like alcohol or marijuana. Don't feel guilty. It is just another way to deal with the depression that causes stuttering. Don't feel ashamed or judge yourself. We are all human, we all look for some form of escape to cope with the pain. be your best friend all the time. I'm sorry for my English, a hug, we are all in the same boat in different ways, I also have that problem.
