Is it normal that when i was a little kid i fantasized about sex with adults?

(I'm a girl) When I was in, like, fifth grade, I was becoming interested in sex. I didn't understand all the details, but I just knew that I wanted it. Y'know, puberty and all that. Anyways, I'd think up elaborate fantasies about ten-year-old me having sex (or what I thought was sex) with grown-ass men. (I didn't know that pedophilia was a thing, so I didn't realize just how wrong those thoughts were.) I didn't fantasize about the boys my age. It might have been because of the descriptions of the dudes in the dirty romance novels I secretly had read.
Did anyone else do this as children, or was I just super weird?
