In a gender neutral bathroom, there is no crime for exhibiting genitals.
If there was an offended child, she should not be in such a place. The crime was looking, not displaying

Post #11 has details from another article: "Sauer faces charges of child enticement, exposing genitals to a child and 4th degree sexual assault."
If you go do your business and then zip up, there's no crime (other than having the stupid gender-neutral bathrooms in the first place.) It doesn't sound like that is what happened.
I'm not sure what "4th degree sexual assault" is. It could be that they went willingly together and they were 18 and 15 years old.
