Seeing I am some what of an expert and maybe a bit slow to respond here.
I have porked several mainland girls. Ages from 19 to 32.
Usually if some girl asks you to go to here or there. In this case Macau. She wants it.
If you are shy, then go to the hotel, ask her before to make a booking for you both and leave it at that.
When you open the hotel room door and find it is a double,queen or king size bed you know for sure you are in.
If two single beds, still not problem. If in the worst case, which would very unlikely happen two rooms, then I suggest the following.
When in the room, make small talk, maybe give her a small present. A fluffy toy always does the trick for me. Then when approaching the room of the room, ask her if you can kiss her. Then the rest will happen. Most Chinese girls havce a love affair for foreign men. They are a status symbol in China.
Then while kissing start wth the hand on the breast and then work downwards. Before you know it you will be in humping heaven.
Works every time....
