As a regular visitor of (german) gay saunas, it is the most normal thing for me to go naked into the sauna and steam room areas. I now have read that that would be considered unacceptable in asia (and therefore thailand.)
Is that true for gay saunas as well?
I've checked the web page of aquarius sauna and saw pictures of boys wearing speedos in the sauna which kind of proves my fears of having to wear clothing (and even worse everyone else being more or less dressed, which kind of takes the fun out of the sauna visit)

what's your experience? Can I go naked or do I have to buy speedos?
