Boyfriend is very... shy? Options

[fadingcolorsx]

So, I'm in a new relationship. It's only been three days, and things are very distant between us. He's isn't very 'boyfriend like.' For instance, we have a few classes together and walk in the same direction when going to those classes, but he doesn't walk with me. We don't talk as much in the classes we have together as we did before we went out. I asked a friend of mine if he's had a girlfriend prior to me at any time, and supposedly he did, but it'd been awhile. So, I don't know. Could it just be that temporary awkwardness that's in the beginning of a relatioship? Or is he just too shy to be more boyfriend-like?
