Good story, one I can connect with. Hong Kong Tourism Board. This is awkward then for both the dressed and the naked ones. I do not know where You went, but Your observations really made my day, being so fixated on the one thing that for most Germans at least for me is the least important. You can wear underwear if you like.
In Hong Kong, there's plenty of information available for first-timers.

June 8, at 7: July 9, at 6: Most females prefer a female therapist and most males prefer a female therapist as well. There was not even 30 cm of space between us.

Many Europeans, and particularly Germans, find it incredibly joyful to experience relaxing activities nude.
