Oh, okay.
I'm 16.
If anything, it was weird, b/c everyone was dancing, and i just don't dance ^^;
yeah, the thing is, the 3 that were on the dancefloor the most (me, will, and jeremiah) go to raves, and we see some of the worst dancers you could ever see. The thing is, even if you are a bad dancer, the fact that you are dancing is what makes it awesome! We don't care how good or bad you are, or what style you abide to, all we care about is that you move to the music. So if you are just embarrassed to dance, next time, don't worry about it, because nobody cares. Dancing is about freedom, and expression, so just go for it. It really is a blast once you get into it.
As for age, I am 17, so im not much older than you (though most people think i am much older). Don't feel left out, or like you have to leave, just because people are a bit older than you. We aren't going to leave you out of the festivities for any reason. Just enjoy yourself and have fun. Talk, dance, hang out, etc. Don't let awkwardness be the reason you don't have any fun.
EDIT: im sure you did have fun, but you probably would have had a lot more fun if you had just let loose a little bit xD
