Man, once you get in that friend zone it's really hard to get out of it. My advice would be to try and hit that anyway. Just be all cocky and funny around her and tease her. Friends with benefits are awesome, but hard as hell to find. The only advice i can come up with here is to be direct with her, don't lead her on, tell her you want to be friends with benefits and not get emotionally envolved. Truth is, it's probably already to late to turn it around so you can get some play, but that doesn't mean it's impossible. Give it a go, what do u have to lose? She won't stop being your friend because you want to get with her. Good luck bro.
