I was in Shanghai last year and stayed at the intercontinental. If you leave the hotel in the evening, and just walk around the "neighborhood", several women will approach you asking if you want "sex massage". I never payed until after the service was complete. It wasn't anything GFE like, but I was able to do some pretty heavy pounding. The hotel staff never questioned, me, although I still felt "funny" walking a different girl each night to the elevators. The biggest ripoff are the pink lighted massage parlor looking places which sit at street level. I would only try them if you can pay after the service is complete. I tried it one time and they ripped me off...kept on asking for more money to continue service. Not fun.
