Is there a meaning behind his hypothetical question?

I was talking to my male coworker, and during our conversation, he started asking hypothetical questions like, “If a guy were to ask for your number, would you actually give it to him, or would you give your Instagram instead?” He mentioned that he personally prefers to ask for a phone number over Instagram if he finds someone attractive. It caught me off guard since it was only the second time we had ever spoken. Do u think maybe he was just trying to keep the conversation going, being friendly, or was he hinting at something more?
