Too soon?

So I've been talking with this guy since the beginning of July, we hung out a few times and really get a long well. He's 40 and I'm 24. We have talked everyday since we matched and we have crazy chemistry. More than that I feel like we have a really great connection, I can talk to him about anything and I feel safe with him. I totally wasn't expecting to like this guy beyond the physical attraction but I do. I just don't know where his head is at. How do I ask him or start that conversation without being the clingy girl who throws out the "what are we"?
