Defensive tone? I have no idea what you're referring to. You doubted my thesis, I defended it, simple as that.
If you are 48 years old and not on testosterone supplements your testosterone is likely so low that whether or not you fap you would notice zero difference. Not fapping in middle age likely doesn't matter because biologically (not mentally) your urge to procreate is likely gone, so retaining your seed wouldn't do much for you unless you were emptying it regularly to begin with. Ignoring that, if you don't fap to begin with or even look at porn, there's no reason you would notice a difference. You are already at baseline. For me though, my testosterone even in my mid 30s is 1000+ with plenty of free test. Fapping does reduce that by quite a bit so the effects of abstinence are very noticeable.
The benefits of nofap that I listed - energy, desire to be social, eye contact, deeper voice, mental sharpness, lack of brain fog, better sleep quality - these things do not create charisma or wit, but they prime your body to be at a level at which you can actually tap into those qualities. That's my point. It's very difficult to have those qualities when you feel completely drained from fapping.
It's kind of like drugs - take a guy who's addicted to something and force him off of it, he will have withdrawal symptoms and over time feel a lot better, but if you take a guy who's never been addicted to it, he's not going to notice anything different.
The reason so many people doubt the benefits of nofap is because they are simply recreational users of porn/masturbation and when they stop, they don't notice much difference. They were never addicted to begin with. Fapping 3-5x a week or even 10x a week is nothing. People like me, I was fapping 3-5x a DAY for well over a decade, since I hit puberty. Do the math - 5x a week for a year is 260 faps. 4x a day is 1460 faps. Not to mention the amount of porn usage in both scenarios - 5x a week @ 30 minutes a session is 130 hours of porn, whereas 4x a day is 730 hours.
You are ignoring the amount of stimulus received when comparing a true addict to someone who is a recreational user. The combination of extreme overstimulus from porn and the extreme dopamine rush from fapping is deadly. This is one reason why porn is released in countries during war as a weapon to destroy the enemy. It completely pacifies them.
