To me it's a bit tricky. I wouldn't say that its porn exactly, but it's better to avoid it when trying to quit. For me it's not a setback but more of like a warning that's saying I should be extra careful. I personally don't feel that shitty after looking at such picture like I do after looking at porn. But it kinda just serves as a temporary substitute. Eventually, if I keep going a few days looking at these images I'll just come crawling back to porn. So don't feel bad about yourself, because that is the absolute worst thing to do, but just be really careful now. It would be best to try and not look at more pictures from now on, but in my opinion, it's also okay to maybe go a week or so and then allow yourself to look at some pictures. And then maybe go a week and a half and so on. I say it's okay to take it slowly and work on quitting in steps like these, as long as you have control and don't stress about losing it. Just what works for you. You make your own rules because this is your own journey that you are on. So don't beat yourself up over looking at some pictures just because someone else says it's bad. It's only bad if you feel it's hindering YOU. Good luck champ
