What is regarded as appropriate dress/undress for the Sauna's and Stream Rooms in the ski resorts. I know that in many European countries any form of clothing in frowned upon. But I also know many Brits are embarrassed by the body in its natural form.
We all come in different shapes and sizes, its nothing to be embarrassed about.
Even Pete is going to go skiing with only a cheese-grater between the cheeks of his backside.
Gogs, I think it depends upon the facilities that you are using.
In the Perelik the sauna's are in the changing rooms, so are same sex. I think here if you want to hang free you can. In the murgavets, as they are mixed, they will prefer you to have something to cover your modesty.
