Over the years I have been to many of the places reviewed in this forum. My recently completed trip took me to three previously untried massage places and also to a favorite, Urban Male. My favorite, hands down, is 61 MALE MASSAGE, (soi 61 off Sukhumvit, Ekamai BTS). The facility is nice, the guys good looking and accommodating and the guy running the place very professional. The massage was good. I booked an hour and a half. We finished (everything) about 15 minutes early and the masseur took note of that and said, "you still have 15 minutes. I'll work on your back some more." That has never happened before. Prices are a little more than some of the shops.
I had read about The Prince massage (off Sahorn Rd., Sala Daeng or Chong Nosi BTS and then a 10-15 minute walk) and decided to give it a try. It is a nice facility and about 10-12 guys available when I visited . Very spendy. 1 1/2 hour oil massage is 1100 with a minimum 1500 tIp. My guy was straight, so only a top, good looking and a very nice build. The massage was ok, but not great and the extra was adequate. But he was very nice. I think 61 male, though with far fewer guys to choose from, is a better place.
I tried a newer venue, Waternest Massage, (soi 39 Sukhumvit, Phrom Phong BTS). There was a selection of six or eight guys and the facility was good, but still seemed to be a work in progress. I had the body scrub and oil massage. The prices are about the same as 61 Male and the massage was good. Not outstanding, but worth a visit.
As is often pointed out, ones experience varies widely with your randomly chosen masseur from a constantly revolving pool of available guys. I very seldom have been able to have a second massage by a guy I liked on a next trip to Thailand. But each massage is also an adventure much like a blind first date (and you're buying diner!) Hey, that's part of the fun.
This trip also took me to Phnom Penh (a great city if you have not been). I don't know that it has much of a gay scene or at least I didn't spend time to ferret it out. I asked my Tuktuk driver to take me for a massage and when I arrived I requested a masseur. I don't know if he was gay or not-I was just interested in a good massage-and it was one of the best I've had.
