Am I Bi? (yes there are probably a thousand questions like this ..my bad!)?

Alright so I think men are attractive but I am also ually drawn to women who are butch and I don't know whether it is because they act a lot like men or not. I also think some femme women are attractive. I've had crushes on girls in the past and i could have sworn they liked me back but i mean i didn;t want to do anything in case i was wrong..so i don't know what to do, I want to have a relationship with a woman but i don't want to be labelled as a straight chick who is just experimenting..the thing is im not sure if that is a true statement or not
