When you watch others fuck you are the cuck.
Pornography destroys your interior psychic world and replace it with a prebuilt disgusting one.
All that "no-fap" is bullshit, the real problem is fapping to porn, not the masturbation. If you feel the need to fap 10 times a day, then do it, but with your own fantasies.
Just try to remind your childhood and your pre-adolescent period, at that time you didn't need porn to get turned on. Now, if you're accustomed to porn, it will be very hard to simply masturbate without it.
The thing is that your creative power, comes mainly from your libido. Your sexual fantasies can be easily converted to a powerfull energy to create, think, or do other things. Sex takes an important part of your psyche, and is at the origin of a lot of its contents. By imposing its own degrading images and not letting you create your personal ones, watching porn will slowly degrade you're ability to create, because you will be used to have a pre-made material.
It's catastrophic because it impoverished your brain, you became lazy because all the images are available, and also you became more and more perverted because to be turned on, you always need more powerfull and chocking images.
Porn is bad for your psyche, and bad for your creative power. You should try to progressively reduce your consumption, and try to masturbate without it more and more until you're totally disinfected.
