I would advice considering your relationship now as it is, and what you would like it to be. Do you enjoy the way she behaves around and touches you? You are in love with her: what does that mean for how you'd like to interact with her? what do you want to be/do with her? You absolutely have a right to speak up and set boundaries and say what you would or would like to happen. I would definitely consider that much more intimacy than I would expect from friendship, even from a close friend - even the cuddliest friendships I've known rarely involve regular sleeping together or ear-biting, for instance. but I'm not sure that it's possible to know what she means by it/whether she wants something more unless you talk to her about it.
