Fapping is signalling to your brain that the way you are right now, is good to reproduce and that makes your system stop working on making you better.

No fapping signals you have problems with reproducing, which is like you telling your body "Hey mate, help me out here, i cant do it on my own, you have my permission to make me better" And that results in you looking more attractive, having cleaner skin, acting more confident and many other things.

It's common sense really. Use No Fap to find a girlfriend, this is what this whole thing is all about. Going on 100 day streaks is just pointless.
