<human>: Can you condense the text into three sentences or less?

Me: 16, Him: 17, in a relationship for almost three months. I'm rather... Inexperienced with the whole relationship thing, so I appreciate the help, reddit. 

I guess I'll start off with saying that he's technically my first boyfriend. He's been in my classes pretty regularly since 1st/2nd grade, so I know him pretty well. We dated freshman year, but were both immature and scared shitless so we pecked like, three times in eight months. I eventually dump him, he gets a new girlfriend, dumps her after a year and a half, does some heavy partying, and we get back together. 

Our relationship is much more successful this time. We don't necessarily have values that line up, me being a very conservative Christian and him a more moderate agnostic, but we connect great on other levels, such humor and physical attraction (hehe). 

Unfortunately, I'm finding myself falling for him really hard and really fast, I think, although it could just be a case of "yay! First real boyfriend!" As a result, I want to be around him and making out with him ALL THE TIME. I'm (I think) successfully avoiding being the overly attached clingy girlfriend, but it's really, really hard. I normally dislike physical contact with people outside of my family, but this now obviously excludes him, which is a rather big deal for me. He, on the other hand, approaches contact like this in a very casual way, and just likes touching and being touched. He also enjoys making out a lot, but its not quite as much as me, although this could just be a difference in sex (but not sex since I'm waiting for marriage) drives. I know he really cares about me, but I just doubt that it's as much as I like him. 

So my question is, how do I go about with this? Should I pretend to only care about him as much as he cares about me, or should I put my feelings out there in the open, as I think I may love him (yes, I know, only almost three months)? The former feels like a game that I don't really feel right playing, but the latter may scare him away.
<bot>: Dating my boyfriend for the first (real) time. REALLY, REALLY, like him, not sure if he feels as strongly for me. Should I hide my strong feelings, show them, or maybe some combination of the two?
