I have had some interesting conversations with people on this. It seems if you are just a part time nudist that you generally try to answer the door with clothes on. In my family we have always been full time nudists so you forget that you are naked or that it even matters. We always open the door nude. I think the Fedex guy rings the bell for that reason to see my wife lol. I have seen other nudists on forums get angry about this and say that everyone should be getting clothed to answer a door. That just seems ridiculous as its your house.
