This is definitely definitely definitely your OCD thinking for you [take it from a fellow sufferer].

1.) You were a young child.

2.) What you did was not only wholly innocent in intent, I don't even believe it was sexual.

3.) What you did was not sexual abuse in any legal sense of the word. At worst, it was silly and annoying. That is all.

You're fine!!!

I definitely think it is your OCD.
