What does it mean if a guy touches his face a lot when talking to a girl?

Anonymous
I've noticed this sometimes. I'll just be talking to a guy (usually one that I don't know well- not like one of my guy friends) and they will start kind of touching their faces when talking to me.

Specifically kind of picking at their stubble on their jawline and chin, but mostly chin. Like they aren't stroking their chins like villains haha.

They don't seem particularly nervous or anything like a shy guy would.

Has anyone else noticed this before? Does it mean anytbing in terms of body language?
