Lets be Honest you have a problem with porn because you spend hours and hours without thinking about what you are actually doing and when you orgasm you will realize that you have not only wasted your time but also your precious liquid for a pixelated image of a women.
Well I have both good news and bad news.
The good news is you can get rid of this addiction to porn, by have something that gets you into the deep state. What can you do whenever you get a urge to masturbate, well you can do anything that gets you into your deep state. This can be coding, drawing and more, but you get the idea. Or it could be something new that you always wanted to do. Do this deep state inducing activity in an area where you have never masturbated before.
The bad news is that this can take months or even years of failure. Nobody who tried no fap was successful on their first try. After a long period of failure they have cleared this addiction. So do not expect to clear this quickly. You can speed the healing process by doing something that gets you in your deep state.
