I’m confused

So I’ve always like boys and I’ve always been attracted to them, but since I’m 13 (I am 16 now) things kind of changed. Last month I told one of my very good friends that I am bisexual, because I just couldn’t stop thinking about girls. I once made out with a girl when I was 9, but I don’t really remember whether I liked it or not. I could definitely see myself in a relationship with a girl but also with guys. But then on other days, i just can’t picture myself being with a girl. I’m so confused!!! I just want to know if I’m actually bisexual or just sexually attracted to girls.
