As an Asian woman who primarily dates Caucasian men (I was born in America and grew up in a predominantly white area, so I only look Asian), can I take a moment to make a suggestion that may help you avoid the first mistake white guys make when they try to date an Asian woman?
I know this is the internet and people say things online they wouldn't say IRL, but if you want to date an Asian woman IRL and have her continue to date you, may I make a few suggestions based upon idiotic behavior that has been displayed toward me?
1. Don't use the phrase "yellow fever" within earshot. It reduces her from an individual you want to date to just a member of a race that you're interested in, and that's not complimentary. She doesn't want to feel like she's interchangeable with any other Asian woman any more than you want to feel like you're interchangeable with anyone who has a penis.
2. Likewise, do not under any circumstance make a joke about Woody Allen, John Lennon, or ever utter the phrase "Love me long time," etc. I think you get the point. Everyone thinks they're soooo original with the white-guy/Asian-woman jokes, but she's been an Asian woman her whole life, so the bad jokes about Asian women's sexuality began the moment she started puberty and by the time you've met her, these jokes sound like fingernails on a chalkboard, because they're not only insulting, she's also grown to dread them.
3. Now it's been my experience that the men I've dated aren't actually the ones who committed #1 and #2, it's their friends, and an awful lot of these insults masquerading as "jokes" actually come out of the mouths of the non-Asian female friends of the men I've dated, who have jumped to incredibly unflattering assumptions about both me and the man I'm dating and feel no qualms with speaking up by saying something totally racist. So this is the critical part, you need to properly react if one of your friends/co-workers/relatives does #1 or #2.
