Is this normal for someone who is straight?

I know I asked a similar question a while ago but I wanted to add more info. When I was little, I liked a movie just because I thought the boy’s girlfriend was pretty. My favorite character was always the prettiest girl. I have a crush on a boy but the other I was talking to a girl and I kept thinking about kissing her. I don’t think I would mind kissing one. When I see myself with someone for the rest of my life, I don’t see just a boy or a girl; I just see myself with someone. When I don’t have a crush on anyone, I just say that I don’t have a crush on anyone.
