What are you hoping to accomplish? The set of behaviors that will land a guy in your bed for the night is not the same as the set of behaviors that will attract a guy worth dating.
don’t be too stuck up but don’t be a slut either. you have to find a balance. flirting is always fun. and making out is pretty much the same as long as you actually want to make out with the guy, not because you’re too wasted to remember doing so in the morning.
just be approachable. and if you see someone you like go over and say hi to him yourself. this is the 21st century.. girls are allowed to be gutsy too.
