I can say that Nofap does help decrease negative thought patterns and anxiety. Although I will say that since I stopped watching porn, masterbating, etc., I do believe that it has led to a buildup of energy in my body that can make the experience of holding back stuttering more intense. Because there are many emotions behind stuttering for most of us, it’s better for me to just openly stutter and let people know I do so I’m not holding that energy back. Even sometimes when I get really anxious, I spontaneously ejaculate, which is something that never happened before starting Nofap! Overall though, I think Nofap creates a sense of being in control of yourself, and more than other men, which builds confidence. You just gotta find new ways of releasing energy such as exercising, or processing emotions in a healthy way
