Ok I read about the FKK culture but having not grown up in Germany I have a few concerns.
I am an Irish expat, have worked in Munich for over three years. My girlfriend is from Malaysia, but she studied here so she's been here quite long. One thing that surprised me was that she occasionally hangs out in hot water thermal spas with her friends, sometimes her male friends. I was initially very uncomfortable with this. I went to one of these nude saunas once with her out of curiosity. Actually I was more suspicious than curious as I was worried that she could be flirting with male strangers while letting them see her naked. However I was relieved that everybody minded their own business and never even talked to each other.
I am now moving to London. My girlfriend is following me back. In Munich she worked as a translator in a small tech company that has only 3 female employees. During her last month there they organized an outdoor farewell hiking trip for her. It was a small group about 6 guys and my girlfriend. After the hike the group had dinner at a mountain Brauhaus which had a sauna nearby. They invited her for an hour in the sauna and not wanting to seem impolite she joined them.
I was quite disturbed when she told me the next day. Seemed to me like a bunch of horny nerds just wanted a chance to see my girlfriend naked before she left Germany. My girlfriend said not to worry as she sometimes went to the sauna nude during her university days. However she said it was less awkward as she seldom met the guys she bumped into while at the sauna, they were mostly acquaintances she saw during classes.
She said not to worry as she was not going to meet them again anyway. However they do have her Facebook... And after the sauna trip, she worked 2 weeks before her last day at the office. I am terribly uncomfortable imagining her working and attending meetings and chatting with male team mates that have already seen her naked.
Is this normal in Germany? Should I be alarmed?
