Let us not forget when and why man first put clothes on. Humans wear clothes as a reminder of Adams original sin. To me it is more like the question of men with long hair. There is nothing wrong biblicy or moraly with long hair on men or nudity (as long as nudity is in the approprite place like a camp), but socially, neither is publically acceptable. Another thing to consider about nudity, children, I know a nudist who goes to a camp that includes the entire family. This I am completely against. Children need to be able to function in society as adults. To teach them that public nudity is ok, denies them the privacy that they will need in society. Privacy is a very important part of freedom and spirituality.
Anything that a married couple both agree on is great though. But I will choose to keep my hidious body covered when not in private with my wife.
