I’m skeptical of the whole nofap idea - at least in the “never masturbate again” sense - because the scientific consensus seems to be that masturbation is fine, even beneficial, in moderation. Porn, however, is a different story. It might be more like alcohol: objectively harmful even in moderation, but in practice the negative effects are negligible for most moderate users. You could even make an argument that it has some situational upsides. But there are also people who clearly develop real issues with it - where it starts to affect their lives in negative ways. When it comes to porn, I’m one of those people.
Now, if I stop masturbating, that automatically means I’ve quit porn too - and it’s very possible I’ll see an improvement in my life satisfaction as a result. I can see how someone might then turn into a nofap advocate, but I think the risk there is misattributing the cause. The problem probably isn’t masturbation itself - it’s porn.
I’ve quit both for now, but I do plan to start masturbating again at some point. Porn, though, I’m not sure I should even try to moderate. For me, that’s like an addict saying they’ll only try a little heroin.
