Is it normal that i want to eat my best friend out?

Dude, you got friend-zoned. Or what I like to call Brother Syndrome, or BS for short.

Nothing you can do to change that. Be prepared for long phone calls about the guys she is dating, and how she appreciates you always being there, but refuses to see you as more than a friend. She won't take your feelings into consideration when she talks about other guys. And she will become confused when you become short with her, and wonder why.

Then she'll find a guy she wants to spend all her time with, and the calls won't occur as often. Then you'll find out from a facebook post after a few months have passed that she is pregnant. But by this point you've come to terms with everything. A few more months pass, and on the rare occasion you do talk, its as if nothing had ever changed...

And then 3 years pass, and you keep up with her trying to go to school, and be the leader of her little family, in a dead-end job, but the magic is gone a little bit. Then she'll come back into your life, tell you how unhappy she is to be with him, and her life in general. You support her like you always have, tell her she's still beautiful, and you'll hit a nerve with her, because she doesn't get compliments from the asshole she's with anymore, and she'll thank you. But because you did that, her "compliment" tank will be filled up and she won't understand that its the guy she's with making her unhappy. And you get to just sit back and watch it all play out....

If you could bag yourself a fuck buddy, go for it! A rare opportunity indeed.

If she made it clear that she doesn't want to date, I think it's safe to assume that she doesn't want sexual contact either.
