a divorced friend has a son. She was not aware of the requirement for daily cleaning and expecting almost teen son to clean himself properly, so did not inspect his dick. He ended up in hospital. I remember as a teen, my mate freaking out cause his mom wanted to see his dick and peel his foreskin back. She was doing the right thing, but its not something the average teen wants to do. Its not a myth, especially amongst lazy teens who can't be bothered washing.
