Some things happen in childhood that we realize later were wrong. You didn't continue pushing her to do what you wanted. Real abusive people don't stop their abuse for usually a long time & most times have no feeling of wrong doing at any time.

You learned from that experience....when something happens in our past that seems like abuse that isn't ongoing it's ok to write it off as child curiosity....but it would help to work through all your thoughts & emotions regarding this in therapy
