I've been to many in coed saunas in Northern Europe. They almost all have coed showers, either booths or open ones. the best have coed baths of various temperatures, beds for resting, steam and many types of saunas, all nude and coed, coed changing rooms too. For some reason, that is where it is the most sexual, when we are both taking off and putting on clothes. However I have seen some wonderful views of women and girls in these saunas. I have to say women washing themselves is very often totally beautiful to me.
