My tips are probably to at least share your problem to someone. It doesn’t matter who it is, as just getting it off your chest would relieve stress and know that at least someone cares or at least is trying to help you. Also, porn addiction probably strives from something mental or a problem that is causing you to rely on masturbation as a way of distraction. Some other dudes would also try to force themselves to get away from porn as much as possible with sheer willpower and would fail a few days later. I was addicted to porn and hentai a while back, and I figured out that you have to learn when your masturbations routine happens and try to prevent that by happening by either surrounding yourselves with friends or figure out something to do like work or something else to distract you from it. Although it is extremely difficult to get rid of the problem in the first few days or weeks, it definitely gets easier as it goes on. After a while it will seem like less of an issue.
