Is there a such thing as bi-curiousity?

My friend thinks Im bi!!! But I dont wanna be.....I was a and bi-phobic....for the majority of my life and then I acceptd my friend as who she was!!!~ But now I look at her diffrently....I dont know if I like her....cuz I kinda think thats a little discusting! But sometimes I catch myself thinking about her in a weird way. I try to snap out of it.....but sometimes it just shoots back at me. BUT AT THE SAME TIME ...I THINK 'S, BI'S AND LEBOS ARE GROSS!!!! (no offense to anyone out there)HELP.........whats my case?
