It was a crazy realization that I had over 5gb of porn saved to an external hard drive. I didn't see a problem because it was all different from each other. Nothing was the same so my mind believed I needed it. When I started this journey, it did take a couple days of convincing myself, but I deleted it. All of it. Videos, images, links, everything. When it was all gone - my mind panicked. Almost like I could hear it sobbing and thrashing about. Since then it's started to calm down. No comments needed; I just wanted to share a positive story.
Congratulations on taking a very strong step forward and freeing yourself from P! I would also recommend doing a DOD wipe of the free space. This means it can never be recovered in the event you have a moment of weakness.
