So go to friend birthday, chat up friend's friends make good impression on a cute girl, not my type at all so I don't push it. The next morning I get a text from birthday friend with cute girl's phone number basically saying she wants to have sex. Awesome. Then I realize I've never had a casual sex, I'm not sure how to progress this. I was really fat in the teenage years, very religious parents, ect. Sex was always a taboo topic, that I'm still trying to figure out at 24. Casual sex is a foreign idea to me, the last two girls I was with also came with months of relationships. I asked my friend to give me some info on her, birthday friend said not to worry about that she just wants to fuck... Which is strange to me as I only know this girl's name and phone number. My birthday friend thought it was strange that I would even want more information on the cute girl. Which leads me to believe I have no idea what the fuck I'm doing. So I'm just looking for some tips and advice, do I take her out? Or just invite her over for a movie and have a few bottles of wine standing by?

EDIT: This is good, I'm beginning to get the mentality behind this thing.... I think. I'll let you know how it turns out.
