Try google: a traditional Thai massage involves a lot of gymnastic moves more painful than pleasurable. But if you want learn to kiss your own ass, this would be the route to take.
Per Wikepedia: "Note: The traditional therapeutic practice of Thai massage should not be confused with the sexual service of the same name that is available in some hotels and brothels. Sometimes the traditional therapeutic Thai Massage, or ancient massage, is referred to as "old lady massage," while the sexual practice, which has nothing to do with therapeutic traditional massage is called "young lady massage.""
The only ad's I've seen in Calgary for Thai massage have been from the RMT and therepudic massage places. Where did yo see the reference?
