talking to
this doesn't mean just talking. it means talking about dating. if you're talking to a boy/girl/member of the preferred gender, that means you guys are a thing and haven't made it official by going on dates just yet.
Example:
Person A: "So, how many people are you talking to?"
Person B: "Just Adam right now. I think he might ask me out soon."
