Which porn is better?

So I’ve been told that porn is really bad for your health and I was wondering what it meant by that. I usually watch amateur or listen to audios when I masturbate cuz I prefer them over pro, it looks and sounds more real. But I’m starting to feel bad because I was told porn is bad for the mind and I don’t want to go into a relationship “depending on porn” to cum and I can’t. I’ve been also told that the exemptions are erotica (stories) but those just don’t do it for me. Is amateur (homemade) porn and audios bad for you?? Or are they just talking about pro?? This is stressing me out I don’t want to become dependent.
