bi sexual?

I need advice. I feel like I'm interested in both genders but i also feel like I'm not. I don't really know how to explain that in any other way. So here's the big SOS:
I'd love to experiment, but i also would never want to use someone who knows their sexuality just so i can find mine. 
Have any of you experienced this? How did you "experiment"? And for the lgbt ladies, would you feel used in this situation?
