Two Months

We've been seeing each other about once a week for two months now. I'm not certain where to consider us. Are we exclusive or not? I wonder because if not, there are a couple of people that I'd like to go out with. I'm not certain where that will get me, but I feel it's a little early to be asking about where we stand. I don't want to scare him away, but I also don't want to make it seem that I'm interested in dating all of these people, especially since the whole situation with my ex. I don't know what to do or to think. We are having sex and often, but that doesn't mean much of anything. What should I do? Should I ask him or should I see him for another month or so before I broach the subject?
