<human>: I met a pretty fun guy recently through some friends.  We recently became friends on Facebook and we have hung out a couple of times with other people.  I know that he is into me and has been flirting pretty heavily lately, but he isn't someone that I could see myself ending up with long term.   The personality is great and I think we could be good friends, but there are a few things missing that I can't get from him.

I think we could have some fun...maybe even be friends with benefits, which I'm considering, so I'm interested in seeing what happens.  I invited him out to a movie which I had an extra ticket to, so there's the chance that he might think that is a date.  I don't really know what it is.  We're not to the point where we would talk about feelings or anything...so far it's just been a brand new friendship developing.

At what point do I need to make my intentions clear?   What if he makes a move on me during our outing?  I wouldn't want to immediately turn him down since I'm not necessarily opposed to that...but I wouldn't want him getting his hopes up that it could turn into much more.  

How do I approach this without hurting him but leaving the door open to other things?

Can you condense the text into a few key points?
<bot>: This guy is into me but he's not relationship material to me, at what point do I need to make that clear?
