Dear Cum On My Face 
I honestly don't know why American born Asian females tend
to date Caucasian men.It could be something as simple as there are
many more white guys than Asian guys in west? Or perhaps some
Asian-American females still cling to some negative stereotypes
when it comes to Asian men. Including those that are born and
raised in America?.
Perhaps there are some Asian-American females on this forum that
could contribute their opinions on this matter. Since I am not
about to try and understand how any woman thinks. Or act as their
self appointed spokesperson.
Asian guy and ang moh girl relationships are uncommon in the
US. But are much less rare than they are in Asian
countries.
On a lighter note there is a popular reality show on US
television about an Caucasian woman married to an Korean-American
man and their eight children called called Jon & Kate
Plus 8.
