Again- I have not read the charges and findings of the court trial but it seems likely to me that the reason it was called 'attempted rape' was that nobody present knew/knows about penetration. If that is true, it follows that each of them adjudged it on the basis of what they did knew, whether from experience, observation or peer tales.

So, the little girl saying they had "put their willies inside her' may well not have any idea of what penetration actually is.
