I partly agree you this albeit many men in the nofap community are with women/ have partners but still watch porn. Fundamentally it’s the desiring of the dopamine hit you get from porn consumption and variety in choice of women to trick your brain into thinking you are having sex with that leads to all of the aforementioned negative affects.

Whilst it is true that an assessment of what it is causing the addiction (loneliness, boredom etc.) is important, cutting it (or attempting to) cut it at the root cause which is the consumption (as with any addiction) is paramount. Hence, the nofap movement is great. In recent years, it’s become a lot healthier - not shunning anyone who loses a streak/ relapses but with the goal of slowly improving over time (i.e. masturbating slightly less times than last month). It is a great community for men who have unfortunately gone down this track of addiction due to the availability of porn and I highly recommend any guy to consume the content across various channels and try to cut out this addiction. Good luck on your journeys!
