Still strugglin myself and I have a very sexually active relationship (last sunday i finished 3 times with my gf)
I started young as a kid and had ED when I first started being sexually active, I cut back porn and masturbation and it got better.
Recently the consumption got worse again with being alone working remotely in covid and being bored af. I dont get ED anymore (unless for some reason I beat an insane amount for a few days), so I have to fight for a more internal reason to stop.
even in a committed relationship if I dont use it for just a week I can feel a huge difference in confidence and overall happiness. It feels terrible when your dick is picky when you are having sex ("I have to get it in soon or it'll go soft") and vice verse it feels great to know that its going to work for you 100%. I think the addiction is highly correlated with a feeling of passiveness. It comes to me when I passively want thrill or excitement but don't want to actually do something actively to make it happen. The result over time is that it will pacify you and hold you back from actively achieving things, even unrelated to the bedroom.
Obviously remembering all these things and benefits will help, but the slipperly slope of that desire is still pretty strong. Best practical advice I could give to you is that if you need to, masturbate without porn and only your imagination. If you are highly addicted you might not be able to do that at first. So if you go soft, leave your room and go about your day. Doing so will prevent you from unnecessary stimulation, but still give you an outlet to let loose if necessary. I think removing porn can help unveil to you how messed up ur mind has gotten
