You have sex with more women than the average Chinese man could ever imagine, and you become an enemy.
On one hand, it hurts people.
Your having sex with whichever consenting adults who are at last getting the quality attention and sex many of them have never experienced before - great, a good read that countless other expats can agree with through experience as can the girls involved.
I heard that a guy American? There is nothing wrong with you screwing as many women as you want to, as long as they want to too.
They are ill informed and make you look every bit as daft as those bigots who held a witch hunt for you.
Go to find your laowai fuckers to fuck you hard.
