Massage explainer on ShamelessMack’s blog: https://shamelessmacktwo.travel.blog/massage-glossary/

"Prince, Hero, and tons of others. Massage minimum tip is often 1000 or 1500 depending on the place, and then a fee for the room 500-800 depending as well. In all the above, find a mamasan you like and have them give advice. Or have someone interpret for you."

The Prince Men’s Spa gets most votes, though it’s expensive and there is at least one report on cramped room and leaky AC. Oil massage 60 minutes: 1,100 baht, minimum tip 1,200 baht.

"For hygiene and facilities  my vote goes to MyHero in Sukhumvit soi 11,  bit of a distance from Silom ghetto but easy to get to. Like Prince, they tend to glance over the massage part and go to second act as fast as possible."

"The highly rated (on Travelgayasia) Magic Touch opens at 10:00 each day. Not much choice in the first few hours. Easy to find; it’s off the soi that runs up the side of Le Meridian hotel."

"Paradise  on Silom Soi 6 opens at 10am (according to google). It's not a full-service gay shop as Prince or Arena or Senso, but it's very gay nonetheless, meaning "things" WILL happen there….."

"Senso: 60 minutes’ oil massage was priced at 1,000 baht with a recommended minimum tip of 1,200 baht." 

"Tarntawan Massage, not to be confused with Tawan Massage inside Soi Tarntawan. About 12 service providers visible from the front of shop, majority of which were men. Foot massage: 250 baht for 60 minutes. Baby oil massage: 500 baht for 60 minutes." Small shower, low water pressure.

"Bangkok Massage is in the epicenter of action, right under  Lucky Boys. Along with Arena and Senso open early afternoon, like 2 or 3 p.m. 

Adam and Nakarat may be opening earlier, like noonish."

VK / VCK / CK – less recommended, as is Indra.
