these situations confuse the shit out of me..

but he kept looking at me with this mix of confusion and intrigue on his face

This, right here? This and the description of the awkwardness sounds like maybe he's shy and had one of those "leaps of courage" moments.

You know the ones. Where you stand in the background and go "come on, just talk to him. You can do this. Just step up and say something. Say anything." So he did it, and then realized once he got that first thing out, he hadn't thought of where to go from there.

Thus, awkward, but interested.

I could be way off base, but that's what it sounds like to me.

And, not all guys that are into men "seem gay".
