If a guy hasn't asked to be exclusive after 8 dates shoul I move on?

I've been seeing a guy who came from Aus for 8 weeks now. We've been on 8 dates (we hang out once a week). We had sex after 5th dates. But we have not had the exclusive talk.

I asked him the other day "Are we in a situationship?"and he said "Maybe? I didn't think about it haha"

Just so you know, I'm from Korea and Korean dating culture is more conservative than Western one.
