What does 😋 mean from a guy in this context?

So it was totally random, I just sent my guy friend a pic of some change I got from work, and he said "oh nice." Then on a separate message sent 😋. I asked what that emoji was for and he said "for fun😋" did the emoji again. I was just like okay lol haha. I'm guessing he's trying to flirt? I'm not sure.
