There is nothing "bad" about it. However from my experience, it does lead to an objectified view of sex, and not one of overall satisfaction, it tends to be on the side of sex addiction, peak and crash type of feelngs, as I'm sure you've noticed. It's probably not the best choice of support for connecting with women.
When I did that NG crap, I did watch less of it, however there was a judgment in that community about porn being "bad" - which leads to repression, which can lead to binging on it.
If you wanna watch it, watch it, don't resist it, that's even worse. Or just let the feeling pass and see what happens, which is the best way to go to break in habit in the long run, given that you've the awareness and control to do that.
^THis!
Porn at the end of the day is an easy access to naked women any time you want. You know its there, there's no religious insitutions telling you of its evil and threatening to cut your balls off if you watch it.
You're going to want to watch it. And it does have negative effects...affects... w/e its not good for you.
