It's like breaking any other habit, hard for first few days later you wonder why you ever did it. We're very adjustable breed.
Didn't fap for 10 days couple years ago, recently didn't fap for five days. Thing is, I only fap when I'm at home so... going on permanent around the globe vacation would probably mean I'd never fap because I don't have such habit outside of my home. Having sex is completely different than fapping as everybody who ever had sex knows. Fapping only at home, having sex wherever I can without getting arrested.
Keeping yourself near release is called edging, internet whores taught me that.
Fapping isn't healthy but it isn't particularly unhealthy either, it's just some stupid habit of modern man. Like eating excessive amounts of sugar for no good reason other than temporary pleasure that lasts for extremely short amount of time. Same with fapping, you invest bunch of time for minimal pleasure and after some time you get used to it. You won't go nuts if you don't fap regularly contrary to popular belief.
For global promotion of masturbation among modern youth, making it cornerstone of their daily activities I blame United States. Porn, masturbation, eating sugar, insensitivity to violence, narcissism, ambition, hypocrisy, all those things exists around the globe but American marketing experts sold it to the entire world as a way of life. It goes to the point that people who don't do that are considered weird. Which is exactly why millenials around the world find it hard to undersand their parents because their parents weren't poisoned by American way of life.
