The ad states that it is non-sexual, but, as I've learned about Thai massage, this does not necessarily mean exactly that, at least according to the North American definition.
I made an appt a while ago with another Thai massage practitioner, and only after I had done so, did I notice that a release was available. The thing is, it's not a sexual thing, per se. It's about energy and that type of thing. I actually spoke at great length with that woman, and she was quite earnest about it being a legitimate, non-sexual part of certain Thai techniques. Curiosity got the best of me, so I changed my original appointment to include that, and wasn't disappointed, but YMMV. It was fully clothed, no touching, but what I thought would be quite clinical turned out to be very enjoyable. The lady got up on the table, sitting in front of me, and put her legs along side of my body and did her thing. She encouraged me to grab hold of her legs, be vocal, move around as much as I wanted, and generally let myself go.
I talked to her again a little after the appointment, and she assured me it's something that is taught in Thailand (where she studied) and has to do with one's sexual energy, or blockages, that sort of thing. She didn't charge any more for this type of appointment than a 'normal' Thai massage, either.
As for the one in question, you'd have to inquire yourself, and I wouldn't be afraid to - but don't use typical language or acronyms would be my advice.
