I'd let him know you haven't ever kissed someone before if you feel it is heading in that direction, that way he knows and it's a good hint to what you want.1THIS IS NOT RELEVANT ANYMORE

If you two decide you want to go out more, then tell him you want to discuss boundaries. This way you can make sure things don't get out of hand and go faster than you'd like.
During the date, just be friendly. Don't make it physical, and it's unlikely he'll make a move. The first date really shouldn't involve kissing anyway in my opinion, it should be more like flirty friends, because neither of you really know if you want it to last yet.
If you want to pull away after the kiss, pull away and end with a hug. That way it won't seem like you're rejecting him but then you still can control what's going on. If you're not attracted to him, then just don't kiss him. Don't waste your first kiss on a guy you don't even like.1THIS IS NOT RELEVANT ANYMORE
