A bit of time spent in China will do that to anyone. I guess as long as you walk away honestly believing that you've had a genuine experience, the reality is not relevant. If you get into your taxi completely satistisfied and always remember what you (think you) did, without any reasonable doubts, the objective has been achieved.
Myself, I can't see the attraction of paying a large amount of money to be with a girl who clearly isn't enjoying the experience, is scared, unskilled etc. I know her family would probably receive a significant amount of money, but I would feel too guilty afterward.
