It's kind of a taboo subject but from my research and experience cutting back on masturbation and porn (quitting porn if possible) is one of the quickest ways to make yourself and more assertive person who is willing to question bullshit.

What does cutting back mean? Well it's different for each person. If you masturbate 5x/day try cutting back to 1, if it's 3x/week try cutting to 1x/week. Cut out as much porn as you can, no porn is the best thing you can do.

I would encourage you to do research on why this works but some basic premise is that when you masturbate with porn you are rewarding your brain with dopamine even though you haven't accomplished anything. Because you are rewarding it the brain assumes whatever you are doing is causing you to win so it cuts back on methods to motivate you or encourage you to "stir the pot" so to speak.

It is weird that the mainstream pushes frequent masturbation to porn so much, it makes you question if they are doing it on purpose to keep people complacent and docile.

All I can say is try it for yourself. The results usually speak for themselves.
