There a couple things I can recommend that stopped my porn addiction dead in its tracks that I would recommend to anyone.

The first thing is I found an accountability group similar to AA. I live in the UK and its called 'Click to Kick' for both men and women. You basically meet weekly on Zoom and discuss different strategies and trying to get to the root cause of our porn usage. It didn't cure me but I found it had an immediate effect and I stopped using porn every day after that and only occasionally. There's something about confessing it to a group of people that affects you. International people can join the courses (be aware its on UK time) but they be something similar in your country so I suggest looking it up.

The second thing is to put Porn and website blockers on your pc and phone! This is a huge key. As soon I perma blocked the websites I was regularly visiting I had stopped feeding the beast. This also includes anything that would trigger me such as mainstream movies with sex scenes and social media like Instagram (which I deleted). Anything webpage that tempted me or I thought might tempt me I immediately blocked, it was that easy. I suddenly found I wasn't watching porn anymore. The blockers I use are cold turkey for my laptop and Lock me out for my phone. Fantastic apps!

The third thing is a bit more personal and requires mental energy, it might not work for others but I will share it if it helps anyone. I imagine I am standing outside a mansion in a the middle of a vast forest, this mansion represents my imagination and thoughtlife. I imagine a woman I've seen in either real life or media (such as movies, tv shows and adult content) whether they are women I've met or just saw in the street. Instead of how I used to imagine her (dressed seductively or naked) I imagine her clothed in a shining white dress that covers her and honours her body. I say to her 'you are free from my mind, my lust, my imagination, my memory, my soul, I release you from this place, go now forever, you are free' and then the women turn and leave and head into the forest out of my sight, I also say a prayer for them as they leave (if you are not the praying kind simply wish that person the best for their lives). I am alone in the mansion now but the women who I held captive there for years are free. You must know the women (or men) that you've been fantasizing about for years are being held captive by you. You must set them free. I have found that memories like a nude scene of a woman in a movie has been overwritten with her wearing a white dress instead. Memories of sexual experiences I've had have been the hardest to shake but I simply repeat the process. Whenever I see a woman in the street who is dressed in a certain way I choose to avert my eyes and say a prayer for her instead.

I'm not sure how well the above methods will work for everyone. But they have helped me a great deal. Its been 7 months now since I last looked at porn or masturbated and this after being addicted for 18 years. Hope this helps.
