<human>: Give me a shortened version of the text

I just moved to a new town for my job and I am having the time of my life. I am dating this guy I knew from college but we are super casual. We are on the same page with not wanting a relationship but we are exclusive when it comes to sex. I think we are equally attracted to each other. Enough to keep seeing each other, but not enough to seriously date. We have casually dated for about a month. 

The problem is, I have never casually dated before. I have always been in serious relationships and I have no idea how to date someone without seeing a future in our relationship. I don't want to hurt anyone's feelings. I'm just having fun but I don't know what the social norms of casual dating are. 

Should I not date the guy if I don't see a future? But then I always wonder if I might like him more later. 

Should I move on and try and find someone I might be more compatible with? 

How do you even call off a casual relationship if nothing is technically wrong?

Can I still give out my number? I've been saying "oh, I'm kind of seeing someone" and I feel really awkward since there have been a few guys I'd want to get to know but I don't know what is acceptable.

I realize this might just be something I have to talk to him about but I feel like he's going to get butt-hurt about it. So a part of me wants to just hang out with other guys and then call it quits if I like someone better but I feel like that's a really shitty thing to do.
<bot>: I'm just looking for some advice/tips on casual dating. How do you keep your options open while casually dating someone?
