thanks again for that clearing up.
A by now more accurate listing is probably that well-trusted site:
TMM Society Never Die :: Gay, Thai Massage and Spa, Sauna, Night Life information -its Thai-scroll down till bottom and find lists+links.
It also mentions gay sauna's in Ubon, Khorat, Phuket among others.
Ive done 2 now the last weeks. TROY and TRIO (L. Prao and RamKamHaeng). But it really remains hit or miss without any clue of what will happen or what you can expect.
A nasty thing (IMHO for me) is that new fad of underwear/small towel/(partle) naked etc. nights. Bring some fancy underwear for just in case. Small towels are the worst-even for drying up after showering. Many Thai take 2 and tie them together.
On the plus-many suburban sauna;s offer free drinks and some even some free food/buffet. But they tend to be far more basic as Babylon with its opulent luxury.
