Maybe just be friends with her. As Nero says, be open and honest. Tell her that you're going through a really confusing period of self discovery yourself right now, and that it wouldn't be fair to anybody to get into a relationship but that you would be honoured if she would be friends with you. If you think she is trustworthy, take her into confidence about liking guys. She will appreciate the honesty, and will probably really appreciate the trust you're showing in her.
IMO, an extra friend is always a good thing, and who knows, you two may still be of huge help to one another.
