(Possible Trigger Warning, I talk about what it was that I watched) Is this an addiction? Since late 2015, I've used PMO recreationally. I never had any hard feelings to cover up with it. It was just you know, every teenager's source of pleasure. It wasn't porn either, it was just things like just showing their boobs and verbal teasing. Anyway, with that subsided, I never knew about NoFap and the rules. I thought it was just a website to talk about things like porn related things. That's why I relapsed, because I didn't know it was for the greater good. Anyway, never have/had any urges since NoFap. It isn't really a challenge for me. But I can't really say it's an addiction. But, if anyone else has opinions, go ahead and notify me.
You bring up a good point. I'm kind of in the same boat. I think I reached 90 days. Fortunately, it was not too difficult for me. However, I'm an older man (50). So perhaps my sex drive is not that high. Also, I'm married. So I do have partial sexual outlet. But I was PMOing a few times a week (for many, many years) prior to NoFap. I still get urges, have triggers, particularly when coming across names that sound like P stars that I previously watched... But I'm able to re-direct my thoughts or just hang in there till the urge subsides. So, like you, not sure if I have an official addiction or just a habit...
I think what matters most is your own perspective on it. If you aren't using it to escape/feel good and it's something you can take or leave indefinitely without any urge or compulsion, maybe it isn't an addiction. If you find yourself periodically going back to it without good reason--like it has a will of its own--maybe it is. As far as stuff being "real" porn or not, to me it's all the same. What matters is if the stimulation is artificial. A stripper is a real person, but if she's tantalizing me and it isn't a precursor to sex, then it's serving the same purpose as looking at porn; my brain is stimulated by sexuality, I get the resulting dopamine spike, but I'm not going to actually have sex. My view may be pretty black and white, but that's what works for me.
What's weird is that I have absolutely zero intentions on doing it again. I do like NoFap. For me it was you know, just fun. But still I'm gonna keep abstain and staying on NoFap because of many reasons. I see what you mean by that too.
I myself believe it's just a habit, it was something I didn't know about with the negative side. But, as you said, the days will be easy so I think this should be a breeze.
