What ever happened to 13 year olds?*sigh*?

Okay I think girlfriends and boyfriends are fine when your 13 (also I am 13 kay) but when you are having sex doing that crap it is weird and creepy also why are girls wearing really short and slutty stuff sometimes not always and stuffing there bras (funny story there was this girl who stuffed her bra with tube socks but a tube sock was sticking out her shirt lol) But I mean what happened to playing with G.I Joes or barbies now kids have sex wtf happened to 13 year olds?
