Am I bi?

Okay so, im not sure if im bi. I have never had a crush on a girl like i have a guy, but i have been sexually attracted to girls before. Like "holy crap you're so hot i wanna kiss yo face!" Its not something i try to surpress but it would be hard to come out if i ever did fall in love with a girl. Right now i have a bf who i love but sometimes i wish i could experiment just to see if its true or not.
