Am i bi les or straight? Im scared help?

Ok, i dont know if im a biual or something else but, ok the other day i met a really cute girl like very cute, and i am always thinking about her, on the other side i like hot and cute guys, ok when i accident click on a or gay video then i feel disturbing and scared then close it down, and when on the street i see two s holding hands " im like ewww" in my head, i dont mean to say that but that is my thought, i still have crush on boys and thinking about pretty girl, when i meet pretty girls i get very shy and i get shy with boys too, i dont want to be a or either, i just want to be a normal girl... If im bi or les is there anyway to be come straight, please answer politely and wih respectful please.
