Well, if you're not sure yet don't be in such a hurry to define it. It is completely ok to not be sure. You shouldn't rush such a decision anyway. If you try to decide on one or the other right now but don't feel either side strongly enough you might pick something that doesn't even fit. But having decided it you try to hang on to it too much to even notice it's not what you actually are. Remember: You don't really choose your sexuality - it just happens. Take your time, listen to the voice inside of you, think about it, and don't be in such a hurry to pick a label. I mean, if you absolutely want a label just say you're still questioning. That's also a valid option. And when you feel like you are sure what you are inside you can then pick a label that fits it.
