Potential Boyfriend: Should I Kiss Him?

Hey girls, I have a question. I'm 16 and I have just reconnected with an old acquaintance (through a mutual friend who had no intention of trying to get us together) from a year ago. We have been talking for 3 weeks straight and we like eachother a lot. We've had the boundary talk and the sex talk and all that jazz. We just met for the first time in person 2 3/4 weeks ago and have only hung out twice. We want to kiss each other when we go to a movie today is that too soon? It feels like we've known each other for such a long time but we've only really known each other for 3 weeks and I'm not ready to date him but I really wanna kiss him. Should I?
