<human>: Can you condense the text into three sentences or less?

This guy and I have been talking and hanging out pretty frequently for the past month or so. We are both considering making this an "official relationship" at some point, but we are just wanting to take it slow and get a feel for our interpersonal dynamics before making a step like that. 

We enjoy mostly all of the same things, we get along really well, and we have great conversations and physical chemistry. However, me and him don't really share a lot of laughter or have any particular "fun". We do plenty of things that are very enjoyable for the both of us, like hiking, people watching, discussing art, smoking trees, etc... But there seems to be something missing in the "fun" factor. 

He is pretty introverted and told me right off the bat that he can be shy when getting to know someone new. I think this might have something to do with the lack of a social-spark (for lack of a better term). I am usually a very bubbly and extroverted person, I know that I make people laugh a lot and I always have fun when I am around people. But when I am with him, the dynamics are just pretty mellow/personal/serious.

Do you guys have tips on how I can develop this aspect of our relationship? Is it just something that comes in time? Or do you see this as a personal incompatibility?
<bot>: We enjoy each others' company very much and do enjoyable things together, but our dynamics are always very mellow. We don't laugh together much. How can I amp things up?
