Not “could”, you very likely are or have been porn to somebody. Like really very likely. Chances are just that they will never tell you and you will never find out.

Idk just because it’s “natural” to compulsively consume such both sugar and porn to classify them as non-addiction is a bit wishy washy and kinda stinks to me.
Humans literally have evolved to consume as much sugar as possible and same goes for porn because the human sexual response can’t differentiate between real or fake sexual stimulus. Humans see naked bodies, humans get aroused. No matter wether digital imagery or not.

I read about someone who was proud to not have ejaculated for years. At that point I’m wondering if your brain doesn’t just simply shut off sexual interest

Can’t they read sensor data and infer certain conditions from that? For example if you have a limp or something?
