Here is one message I dragged over from another thread. I think it validates at least partially what the OP is saying.
I am an Australian but I am of East Asian decent. I used to have the idea that I should only date Chinese because of our cultural similarities back in high school.
However when I went to University that ideology has changed. I have begun to evolve and like to try new things. I am not as traditional as I was in high school.
I am now married to a Western European man and I have received disapproving looks or comments from other Asians when I am with him or the other European descendent men I dated.
The worst experience was in Taiwan, where my mother came from. Some people there treated us like zoo animals, my husband was so mad and I was embarrassed because I am half Taiwanese. Now I am not sure whether I should bring him back to Malaysia for vacation, because a lot of the people there are quite busy body and conservative. No offence but it's like this.
But Australia is ok; yes we will stick with Australia. This is not to say no Australian has a problem with this, I am sure there are people who do, but it is not as obvious. Otherwise Europe and Thailand are some of the places where people don't misbehave when they see interracial couple.
There is this rumour that it's more scowled upon by Asians for an Asian man to go outside of his race, than for an Asian woman. However it is beginning to change I think. I see more Asian man dating European descendent woman than in the past, although European descendent men dating Asian women are still more common. One of my dad's friends' son married a white American girl, he is Australian born Sino-Malaysian, as his parents are Chinese from Malaysia.
I have also been labelled as "whitewashed" by some Asians because I am married to an European Man that has been assumed as refusal to give Asian guys the time of day. Even just as latent friends.
As with any interracial couple, the Asian women/European men pair has its portion of stereotypes. I have heard and read about these assorted stereotypes from the Europeans' side and the Asians' side. It is pathetic I suppose, but it can likewise be neat to resist damaging stereotypes. For instance, a European decent man with an Asian woman is frequently stereotyped as having a "little instrument" that he can't intimately gratify a white woman. Or that he is solely into the Asian woman for her compliance and sexed charm. Also the Asian woman can get stereotyped as being regarded too unappealing for Asian men, thus having to be with a European descendent man. Or, another absurd (though sometime accurate, I guess) belief made is that the Asian woman experiences outclassed and detests being Asian, and is with the European descendent man to advance her self-respect and to experience as white as possible.
Now I don't really fit into any of those stereotypes of Asian women I read about. When I went to Taiwan with my husband to take professional photographs the people at the studio have tried to make efforts to make me changed my mind, and wouldn't stop asking me why I didn't choose Taiwanese men? I been to the studio 5 times with my husband, each time I was mobbed with questions of why I chose to marry a foreigner?
While back in Australia, after my parents told their friends of my marriage to an European man I received comments such as "Those white men stole our pretty ladies!"
I don't think my husband fits the classification of those stereotypes neither; he has been targeted by white women but also women of other descendents as well. But it is true that Asian women like him, and they are often after him.
Even the time I took him to Taiwan, the prettier ones were smiling at him, and they were not ordinary smiles, they were trying to hook him, the women did that in Thailand too, and he has also been targeted by Japanese woman.
But I get my share of attention so, I am not really threatened.
