Is it normal to look at females this way?

I'm female and I am some what confused. When I see females that are fit, I can't stop starring at them. It's like I'm secretly checking they're body out. It's this one female that sings, she is so pretty. She has a nice body, I love her hair and her music. Her skin looks so smooth and I don't know if I'm crushing on her or what. It's weird because I'm straight. I love men and it's one guy I love everything about him. His eyes, smile, and sexy body.

I have thought about kissing a girl and a little more. I never did anything with a female or a male. I have been kissed by a male and that's it. I was just thinking why am I looking at this pretty female this way? Am I straight or becoming bi? So confused.
