the line between "child" and "adult" can be blurry. According to the law you were a minor and that has implications for the type of crime the perp can be committed for, etc. But though you were a minor, a 17 year old is not really a child, you know? from a psychological standpoint there is more to it... one doesn't magically become an adult at 18. I know 16 year olds that moved out of their parents' house and became financially independent, and are more mature than some 25 year olds I know who still depend on their parents and don't know what they want out of life. It's more complicated than just turning 18.
regardless of what age you were, whether it is CSA or ASA, it shouldn't have happened to you.
