im 15. love girls sexually and romantically. dont get turned on by guys only by girls dont think guys are attractive. but i keep getting the thought of me giving oral to a guy . so basically everything that i can feel for a girl i cant feel for guys but then i feel like giving oral to a guy. am i bisexual?

i am really into girls all the time but sometimes i think i would enjoy giving oral to a guy mostly when im really horny. that is the only thing that makes me think im bisexual because other than that im straight so then what is up wit me?
