A friend of mine, a female, told me about her experience at a summer arts school workshop where she modelled nude for a class of high school students. She was 27 at the time. She didn't realize the age group she was modelling for until the day of the session. She almost didn't show, but went ahead anyway. She said the kids were very professional and showed great talent.
It wasn't at this school, but I thought I'd drop a link to dismiss any skeptics who might challenge the voracity of the story:
