As someone who suffers from anxiety and spends a lot of time by myself. You are completely right, it’s not that fapping in it self is bad, it’s that a lot of us loners become so self absorbed on a single substance to keep us going, and without it we can’t function. A lot of confident people don’t have the problem we suffer from is because they simply just don’t care. They see porn and masturbation as something that makes them feel good once in a while. It’s very similar to gaming addiction. I feel like a lot of the benefits people are seeing is from actually bettering their life. Going to gym, socializing more, eating healthier…etc. quitting their porn addiction is essentially the starting point of improving their life as a whole.
