<human>: Can you give me a shortened version of the text?

So I just started dating this new guy, it started out as just a hookup but now he says he really likes me. The thing is that while I do reciprocate those feelings (to a lesser extent), I still find myself wanting to hook up with other people. 

He made it clear that he won't be hooking up with others while I figure out what I want us to be, but I'd still like to. I couldn't figure out a way to say this straight up besides suggesting "keeping things casual..." Is it messed up of me to hook up with other people even though we're not *explicitly* exclusive? Any advice on how I can navigate doing this?

The thing is that it isn't that serious of a situation since he's leaving for school in a few weeks anyway... we don't plan on entering a longterm exclusive relationship in any case.
<bot>: Casually dating a new guy, is it messed up if I hook up with others? Gave him somewhat of a headsup..
