If you ever get the chance, do it! Problem is, there are so many taboos associated with it from their cultures. Language barriers, societal standing, no bringing "shame" to the family, etc. In North Asia especially (Japan, Korea, China, etc.), the women are very shy, the ability to communicate with them can be difficult, and they definitely do not want the family to know! They're not real happy if their daughters are seeing a white man, and they totally come down on her if she's dating a black man. It's all about "saving face," and not embarrassing the family name.
