A2A, I don’t normally answer questions by high schoolers because they’re just too green at love to find much use in knowledge and frameworks, and instead should just muddle through their situations and hope to learn from them.
But no, there’s nothing wrong with being attracted to any girl, physically or otherwise. People worry about the genuineness of the feelings, does he just want me for sex, but really, especially in high school, the vast majority of kids couldn’t manipulate the pants off a Barbie doll, much less a real girl. A few of them learn how to do it, but by no means most.
So no, don’t let your attraction get to you and make you think of yourself as a bad person. You’re just doing what nature intended you to do.
