Angelina no I wasn't being sarcastic, I was just trying to get my head around how it works. That's why I brought up the spa / sauna situation in Scandinavia as an example... I thought maybe it was just something that families did together in your part of the world.
In Japan for example, you have to be completely naked to go to an onsen, and it's quite normal to bathe naked with others.
The fact that it IS considered weird in Germany makes this situation even more creepy. So what, he just stands there and watches you like a voyeur? That's worse! I would have been okay with it if public bathing was a German tradition.
