Am I bi?

Ok this is very tmi but I am a virgin and I’ve only thought I liked guys. And that’s still true because I can see a cute guy and get butterflies. But i find girls bodies really hot. I think I fantasise about girls more than guys. Maybe that’s internalised homophobia but I really can’t see myself in a relationship with a girl. I’ve kind of started to feel the same way about female celebrities as I do male celebrities. Am I bi? I don’t know please help me
