My wife and I are nudists. We are thinking about hosting an exchange student. Has anyone else ever done this? How did you introduce the exchange student to your lifestyle?
I would say just tell them that your family is "Clothing Optional" and see if they are comfy with it. Don't force them to see more then they want to.
If you don't tell the agency that arranges for exchange students about your nudity and a student shows up un-prepared for such-you might want to brush up on prison etiquette.
