Exchange students are expected to adapt to their host-family’s culture and try to follow house rules, however, there are limits. Some exchange student representatives do a terrible job when vetting a potential host-family. Or, perhaps, they are lied to.
In this example an exchange student asks what to do in the case of host-family nudism. Answers range from disbelief to telling the exchange student to get out of there as soon as possible. I tend to agree with the person who thinks that the host-family should put their nudism on hold while hosting. If they are unable to do that, then they should not be a host-family. Oddly enough, nudism is an issue that turns up with host-families and/or exchange students. When in doubt, always use caution in how to share your personal culture. Nudism is rare in most countries.
I am staying with my exchange student and her family in Germany. She and I are both 16 and she has a 9 and 21 year old sisters and both her parents. All her family are nudists. I told them that I don’t feel comfortable with them being nude all the time but they said that it is unhealthy to be insecure about your body. The dad is at work most of the time so they say it’s all okay because we’re all girls.
They don’t have locks on the bathroom doors and when I’m having a shower they just walk in to brush their hair or clean their teeth and they see me naked. My exchange student and I have to share a bed and of course she sleeps naked. They said they are borrowing another bed from their friends but they are still waiting another week. They only wash clothes once or twice a month because they only need them for going out. I have to wear the one dress to school for a whole week because of it.
They’re really nice people and everything but I am staying with them for three months and don’t want to feel uncomfortable staying with them for so long. I don’t want to report them to my supervisor teacher or anything like that because I don’t want them to get in trouble. What else can I do to stop having to feel so uncomfortable around them?
Foreign student exchange 
We had a nudist exchange student. Didnt bothers at all. My wife is a doctor and I am a nudist. The next summer his parents invited us to visit them in Vienna, Austria. They were so nice to us.
I’m glad that worked out for you.
Wondering did you know the exchange student was into nudism did you confirm before hand or it just happened
My professional opinion is grow up and let the supervisors know, they’re not the mafia so you have nothing to worry about in terms of confronting them if they are mature adults they would 100% understand, also they are straight descusting nasty nasty nasty.
