its started as Movember a way to raise money/awareness for prostate cancer by letting your moustache grow out during November. Neonazis then invented their own version where they refused to masturbate all November and call it nonutnovember. It was never clear what the point was but it was basically neonazis and 4chan shutins doing a self improvement cult around masturbation. Sort of a "Hitler helped me get off drugs" kind of thing. So now neonazis and right wingers and even just random serial masturbators like OP have begun abstaining from masturbation, porn, and some sex all together. However the main focus seems to be to stop masturbating in order gain the motivation to get a girlfriend. There is some pseudo science involving holding in your cum making you a better athlete. Muhammad ali practiced abstinence before a fight, in the movie Rocky the fighter abstains from sex. But it mostly seems to come from a strange practice involving twisting and tying a roman gladiators penis so he couldn't ejaculate. So its basically white jesus hates sex, and roman gladiator penis magic
