Moving on too quick??

Me and my girlfriend broke up about a week ago, prom was yesterday and so was the after party. she told me she loved me all nght even if we wernt together, but at the end of the night she got with this guy who I F-ing hate and yeahhh.. anyway.
I asked...

my friend if they wanted to have sex, you know as a joke.. but they took it seriously and they are thinking about it!?
if she says yes what should I do? is it too fast or am I making the right move, she is a really pretty girl and a good friend?
is this the best way to on? or should I be sobbing for hours at home xD

thanks xx

Well first of all... forget about that Ho* you took to prom! she obviously has no idea what she wants! Second, Have you ever even done it before? How long have you even known this new girl? I know it is natural for a guy your age to just jump on the first chance that an experience like this pops up with a hot chick... but think with your brain!!! not with your other head! LOL... Do you really want to move that quick with a girl who is considering getting so intimate and personal with you SO SOON? Dont you think you 2 should date for a month or 2 and get to know eachother a little more? You will learn eventually sweetie... a girl that is willing to give it up that fast has no respect for herself! And just think... Dont you wonder how many other guys she moved that quickly for?
