Basically wanting to do traditionally romantic things like kissing, hand-holding, etc. but not wanting anything more than that.
I've seen the orientation lithromantic, but that's only having an attraction but not wanting to act on it, in this situation it is about acting on it, but not wanting a romantic relationship.
Update: I think lithflux might be close to what I'm looking for. If anyone has any other specific term I could use, it would be greatly appreciated!
