Dude....

If you play your cards right, you might up with a friend with benefits.

She's testing you. See if you'll creep out and be a stalker.

Play it cool. Don't be a hard ass, but play it cool. Eventually you'll both do stuff together. Be kind, don't be a doormat. You are both young with raging hormones. Let nature take its course.

If you get creepy on her, game over. Start over with a new girl
