Y!A, what should i do?

alright kind of a long story. me and my friend went to a party one time after it was over we went back to his house to find his little brother and some of his friends having a little party of their own (me and my friend are seniors in high school, and his little brother and his friends are freshman in high school.) anyway we all played some beer pong except my friend. him and i wound up taking two freshman girls home, they were really flirty but nothing happened. the next day my friends lil bro told me one of them said they wanted to have sex with me. anyway, that gril friended me on facebook, and just started iming me today talking about hanging out and stuff. normally i would just ignore something like this, but she is really hot and pretty cool. so Y!A, should i go for it?
