Yeah, I used to be confused, too; my current status is "whatever". That is to say, I simply let things happen as they happen, and no longer bother to attach labels to myself. It's wonderfully relaxing, not having some sort of inner code of behavior to conform to.
So. Relax! Follow your instincts, whatever they might be -- and keep in mind that they might change. You don't have to be any one thing: straight, or bi, or gay, or lesbian, and even if you are, that one thing doesn't have to stay the same. Identity is fluid. Just be yourself, and enjoy your life!
