I've been trying to quit porn since last October. The longest I went without watching porn was all of February. I did that by masturbating everyday, no matter what. This prevented me from getting urges to watch porn, because I was never really horny. Early in March, I relapsed, and I haven't been able to go that long without watching porn since. I've tried the masturbating everyday again but it doesn't work as well anymore. Now, whenever I do it, I just feel gross. Which in turn makes me want something more stimulating, leading me back to porn.
I've been trying to follow as much advice from this subreddit as possible. I know why I'm quitting. I'm quitting because porn makes me feel terrible, and I want to have healthier relationships in the future. I try to get outside when it's nice out. I go to the gym a lot, and I have a community of friends there. I talk to my school friends every night so I'm not alone. I just recently deleted Instagram, because it was a big source of triggers. That helped for about a week, until I relapsed again.
I can't do it on just willpower alone. I'll have random thoughts about porn, and once I've started thinking about it, I can't stop, like my own thoughts are a trigger.
I've looked at web blockers, but all the ones I've found that do anything useful on android cost money. And want to solve this problem on my own, telling a friend or family member is too embarrassing. Is there anything else I can do to help myself?
