Is it normal that as a little boy i wanted a teenage girlfriend

When I was between the ages of 8 and 10 I used to seriously desire a romantic relationship with a girl between the ages of 15 and 19, or in some cases a woman in her 20s. Or at least what I perceived at that age as a "romantic relationship", I knew nothing about sex or anything like that. It was a difficult feeling to describe but I think it was because I wanted a more mature girl who was physically stronger than I was. I never told anyone about it but when I was in public I would smile at girls that looked like they were in high school. I thought sooner or later one would ask me out. Most didn't notice me or didn't smile back, but on the rare occasions that one did smile back, I thought maybe they were flirting with me but didn't want to ask me out because my parent was there.
