Is it normal if im into two completely opposite guys?

I don't officially like these guys but I have an eye on them. I met the first one in class and he's really studious,smart, determined and pretty cute. The way it works with him is I can be myself and do anything I feel like doing and he'll accept it or not even that he accepts it but Im ok doing it with him around. He also makes me feel mature, and just overall a good, classy woman, not to mention, hes pretty classy himself too. I think our class kinda looks at us like theres a thing going on but if you get in between our convo, were either talking about school or joking about one little thing. But you know that feeling of chemistry where you know theres something there no matter how awkward it is or free it is? Thats me and him and i feel when our class ends and time to say bye bye, something big is gonna happen or nothing at all and we'll both be like huhmm, i guess there was nothing there. Then as I was with my friend, I met a little boy who happens to be older than you think. I noticed he was playful (not flirty but like a little boy pretending to fight), and he skates. Then he started talking to me and i wasnt even listening cause I was busy focusing on how cute he is but I was like no no come on Im just meeting the kid however, it probably has to do with the fact that im into those little boy types maybe cause Im a little girl deep inside. So its crazy how Im feeling something for these two since I feel like two different people when Im with these two different guys. How can I narrow it down to who is better for me? When Im with one, Im like ok this one is way better duh or vice versa. One makes me feel like a normal, mature girl like I am & hope to be and seems more serious, long term while the other brings out the little girl I am inside and just wanna play around? Well theres one thing in common with them and thats that they both sure do make me smile.
