okay this just gave me an interesting thought
i was going to say "no, anime porn addiction cannot be fulfilling" and i thought my reasoning was
"it's not real, so you can't be fulfilled by it"
and i dont know if that's necessarily the case, on second thought
so my next thought is, "what about those people who love their cars or roller coasters or inflatable pool toys? you're usually pretty okay with their romance because it's not distressing"
so this would make a distiction between "i love this anime character, he is my husband" and "i love anime porn" as a replacement for "intimate relationship, platonic or otherwise"
one is valid because it's a person and the other is not because it's a category consisting of many different images and stories"
but now that i think about it it's really just emotional masturbation, one-way communication, an asymmetrical structure
so maybe neither are truly fulfilling and i was right all along
but i dont think so
