Hey, you described my own experience!
The first anime series I watched (the best in history, of course XD) was Dragon Ball, and at the age of 6 as well.
I still can remember it as if it was yesterday...
I've seen lots of anime series, but Dragon Ball is the best one (in my point of view). I mean, it's really well drawn, battles are amazing, and the story is good too.
The last one I've been into, and which I've enjoyed a lot is Inuyasha(I don't know if it's the original name of the series, however it's main character's name)
PS: Did you know that there exists a Japanese legend about a monkey boy who flies with a magic cloud?
