Well I've done 3 days with NoFap. Woo hoo!! LOL But I realized, while I wasn't looking at porn videos, I was still doing porn substitutions with erotic stories and a kik group I was in. I guess I'm realizing how much stimulation I find out there, and how many different ways I will find to stimulate those pathways. Geez, I really am an addict....
That realization is what got me to stop. I stopped looking at porn for a year and when I relapsed I realized that, like you say, I was looking at porn substitutes regularly. Made a difference to stop that, as well. If you haven't yet, some great information about addiction, particularly internet porn addiction, at www.yourbrainonporn.com
