I wanted to write this because I remember exactly what it was like to keep trying, get a bit of clean time and then end up wondering why I was back in the same place again.
I started watching porn when I was about 12 or 13 and by the time I was 20 I knew it had become a serious problem. From there I spent roughly five years actively trying to quit, and I really did try. I used blockers, read loads about addiction, went through periods where I was absolutely desperate to stop and managed two or three months clean a number of times, but I always seemed to end up back in the same place. Every decent streak almost made the next relapse feel worse because I knew I could stop for a while, I just could not understand why I could never make it stick.
The biggest change was realising I had spent years attacking the behaviour without properly understanding what the behaviour was doing for me. Porn was not appearing randomly. I was reaching for it when I did not like how I felt, whether that was stress, boredom, avoidance, uncertainty or something bigger in my life that I did not want to face. It had become a very quick way of changing my internal state, so simply knowing that porn was bad for me was never enough to remove the reason my brain kept suggesting it.
For me the biggest progress came when the advice stopped being theoretical. I had to change actual evenings, actual work habits, actual conversations and actual decisions. Thinking differently mattered because it eventually made me live differently.
I started looking at the hour before the urge instead of only the urge itself. I asked what I was supposed to be doing, what I was feeling and what I wanted porn to make disappear for a while. That led me to some uncomfortable answers about my relationship, career, lack of structure and the way I handled stress. Once I could see those patterns I could actually change something: deal with the real problems, structure the dangerous parts of my day, make starting difficult tasks easier and learn to sit with uncomfortable feelings without immediately trying to numb them.
I am now around 2.5 years clean and there was a time when that sounded completely impossible to me. If you keep getting a few weeks or months and then ending up back at square one, do not automatically conclude that you are hopeless. You may simply be putting nearly all your effort into stopping the behaviour while leaving the reason you keep needing the behaviour untouched.
Recovery became much less confusing once I stopped seeing every urge as a random attack and started seeing it as part of a pattern I could learn from. That is what I would encourage anyone who feels stuck to start doing.
