Do these feelings suggest something?

ok so i'm a 16 yr old heteroual girl, totally into guys, but then every now and then there'll be a girl where i think WOW shes so cool and can't get her out of my head. just the thought of her makes me queasy. however i'm pretty sure there are no ual feelings ociated. normally i find girls very unappealing but there can be one who stands out and i get confused about whether i just think they're really cool and want to be like them, or whether it's more than that. is this common, or does it suggest something about my ual orientation???
