Kicking porn is a huge part of this, at least for me. From what I understand of this PIED phenomenon, the 'screen' and images on it are really a huge part of it. I believe men have M'd to their imaginations since the dawn of time, and probably still had healthy sex lives with their partners.
I think the difference for us is that it's a reboot/cold turkey situation, so to kind of reset your brain/body it has to be a break from ALL of it. I definitely think there will be times that I will M to my imagination at some point in the future, but PORN is the thing I'm truly kicking. I am just kicking ALL of it for now because I want to focus on real sex with my wife and getting things in that part of my life where I want them to be.
So, don't get discouraged. You're off the porn, which is big. And the statement "I'm done with it!" is a great one. It is exactly how I feel. I just have no desire to look at it anymore. And you are far less likely to relapse if you aren't looking at images that have no other purpose but to arouse people (men).
