>Being sexually aroused is not art, it is an occurrence in the real world.
Based on the definition I shared, it's not about your feelings. It's the quality of what made you feel that way. An important bu subtle difference.
To take your example, it's less about the chatbot and more about how and what it responds with. If suddenly it's responding based on its remembered experiences and sense of the world, I. E. 'Sentience', we would start to wonder if its science fiction.
Edit: Reply to the commenter below, who unfortunately was down voted. I didn't mean it in that way at all. I mean it as in finding a missing part of your essence, which we all have to do at times. Eroticism is in everyday life if we allow it to be and don't shun away from it, just like courage, adventure, challenge, mystery, and a lot of other essential experiences of the soul, which the modern mass man system tries to erase.
This is like saying science fiction is talking to a chatbot. OP is being a bit pedantic.
