What counts as porn?

I started wondering "what counts as porn?", I know that nofap wants to "overcome porn addiction" but what actually counts as porn and what of that is actually addictive?
from what I have seen:
pornographic movies are supposedly addictive
pictures have supposedly been disproven https://www.psychologytoday.com/ca/blog/women-who-stray/201307/your-brain-porn-its-not-addictive
I do not know about books
I do not know about games
I do not know about just using imagination
and I do not know about just jerking off without using any other stimulai other then manual (off of morning wood for example)

I do remember reading about some masturbation being good for testicular health

 

any answer? any opinions? anything?

 

so masturbating to a real woman is fine then? seems a bit of a strange place to draw a line

 

now this might be a nature fallacy but dont animals masturbate too? if you could source the claim I would be glad
another thing - doesn't that depend on the amount of masturbation? because if it (and by extencion any sexual act that involved it) was harmful then woudn't it be impossible to have an active sex life?

 

why?

 

is the cause of morning wood porn? is hiring a hooker for a lap dance porn? is forplay porn? all of those things usually result in an erection but I dont hear many people calling them porn

 

also, for example, eating a cheesecake makes me feel good, it tastes sweet and I really enjoy it, I want to have more but I just dont because noone is forcing me to have more and its my desition to not overeat
another example is eggs, I really like eggs so I have some pretty much every day for breakfast - am I addicted? I dont think so, because when there was a painc and the price went up, I just stopped buying them and ate cereal for a few months
I may be addicted to reading but I cant be sure because there is not much to do right now then read so when I stop Im just bored, is that addiction or just the circumstance?
how do I know the difference between just liking to do something and being addicted to it?

 

"Masturbating animals usually don't procreate and their genes go extinct - and that's not much different from masturbating humans. Just look at statistic: Population with the highest masturbation has the lowest birth rates."
where are you pulling that animal info from? could you give me source?

"If it's about starting a family and having children, just like in the animal kingdom, I don't think there is anything wrong with it from a biological point of view. If your sex life is just about reenacting porn - that's as harmful as masturbation itself is."
what do you consider as "reenacting porn"?
also, while I belive completely that masturbation can be harmful (at least to the skin and flesh of the penis itself, my friend has a lot of trouble with it), from what I know its all about how much you actually do it, if you could give me a source for how much masturbation is harmful and in what exact ways I would be glad (like I said I know it can damage the flesh and the skin but thats only after a really long period of time, or at least it was like that with my friend)

 

so emotional contact magically makes it not be damaging?

 

oh yeah, sorry about that, got a bit confused

 

"I said the addiction (attachment) is to the sensation it creates within your body. Please try not to agree or disagree with me. Look closely and see this for yourself."
"If the thing in question effects your life in a negative way but you can't stop doing it then that's an addiction"
thanks a bunch for the answer, you have been a big help, again, thanks
