I need middle school advice!!?

[Emy]

Hi, I'm a pretty average middle school girl; 7th grade. Anyway, girls here at my school are obsessing and talking about serious making out, grinding, going to slutty parties. I'm not sure if they are just saying stuff or not. I'm rarely invited to parties. I'm not a weirdo/nerd though, or considered "fat": 5"2 and 95 lbs. But I am a random outcast. At my school I'm considered nice and pretty, but I have no friends there, but I do make a lot of friends outside of school.
I see it all over the internet: facebook, twitter, that stuff, even on yahoo answers about how middleschoolers are doing all that serious making out and grinding at parties? I'm not naive or totally clueless if you know that type. I've known what things like this mean for a while if you know what I mean.
I'm crushing on a guy and I'd like have my first kiss too [[soon preferably. I'm dying over here]]. But I think what I'm really asking is do normal middle school kids do that kinda stuff? Not like I'd have a chance to even if I wanted to... But.. should I be doing that stuff?!
thanks
