Can Boys be Naked in a Sanua?

Can Boys be Naked in a Sanua?
It's optional. With girls, it's mandatory.
in a mens sauna, but a towel is mostly what people wear
If I were in a sauna alone and a young boy came in nude, I would probably leave.....it's a screwed up world out there.
Some saunas require it.
With parental supervision, MAYBE! Nudity is not sexual but many perverts think that it is.
