Man, if you know your Chinese history, you do not have to worry about the Chinese race. There are just so many Chinese people and because of those numbers, the Chinese race has been able to absorb so many ethnic groups so successfully that many of these ethnic groups ''look'' very Chinese and speak only Chinese. How many ethnic Manchus can even speak Manchu anymore?
It is human nature for anyone to "crave" the experience of sleeping with someone outside their ethnic group / culture. It does not mean everyone wants to marry those different people, just want to experience. On this forum, so many bros list all the different ethnic groups they have experienced so far and which ones they want to try. It is the same with women too. It is so damn natural and normal.
So because of this normal human nature "craving" to try something different, I suggest that you only date girls who have had previously slept (and ideally dated) with non-Chinese/non-Asian guys in the past so you can give her something to compare you with her wild experiences. If you are good and confident enough, these girls will stick with you for the long term.
(In a similar vein, some civi girls in HK like guys who got the whoring/saunas/ktv out of their system and want to settle down with 1 girl - doesn't apply to most of you guys
).
