Yeah- great theme - women nude for the purposes of relaxation/wellness .
It's a perfectly natural form of nudity- after all, no better way to sauna than nude- and it's also semi-public but semi-private too.
above all, it's unbelivably cool.
I've been to a mixed nude sauna- and yes, it IS as good as it sounds.
However, if anyone knows of one, I'd suggest (as a good policy) DO NOT name the location, or the establishment.
