hey guys

I'm traveling to Bangkok and Chiang Mai soon and want to try a four hands massage - for the first time...!

But I'm not sure what to expect or what the protocol is....

Like, if sex is gonna be involved (which I assume it is in the right massage venue), then how do I know if the massage guys are top/btm or versatile or is this all meant to be sorted out in advance?

Really keen to try it after a spliff or two, but don't want to be lying there wondering what might (or might not) happen stoned out of my mind, if you know what I mean...
