no havent tried it, but i know the place...what I think is the case in china is that if you ask for a VIP massage in ANY hotel, they will charge accordingly, maybe 1300 yuen more or less. This will include complete VIP treatment which is scrub massage, blow, fuck. I may be wrong, but I've seen seemingly 'respectable' hotels in many places in China this is standard operating procedure.
If you cant communicate just put your thumb and index finger together, then insert the other index finger into the hole...
CSL- chinese sign language for fuck.
