If you are into shallow, one-night-stand type jocks, then I have no recommendations for you.
Hot white guys can be into Asian guys but you have to get over the barrier in their subconscious. When it comes to approaching strangers, people are naturally comfortable with the appearance that they are used to. I'm not referring to living in multicultural cities like New York and LA. Even in these places your main interactions are with your family (same race), relatives (same race) and friends from school (most likely same race). The social barriers have come down but people are still hardheaded where political correctness doesn't apply. You might think this is just a problem with Asian people. Some white people also complain about why Asian people only stick to themselves. They just aren't as vocal about it to remain PC.
That being said, I don't think people are racist or xenophobic. If you follow the general rules of dating for interracial relationships, I'm sure you will be able to get along with someone you are looking for.
You probably know your "level" with Asian people, but think about what is your level in a pool of white people. Being visibly different gives a challenge because you may not have facial/body structure that other people view as sexy or attractive. I'm going to generalize a bit but most white people and Asian people like blondes with defined facial structure with a toned body. Now, how common is this among white people? I would say about 10%. How about with Asians? Take the blonde out of the equation and I would say still less than 1%.
Don't have round eyes, long lashes, pointy nose or muscle body? Too bad. Accept it and think about other ways you can raise your level. Many women marry older men not just because of their money--older men are more experienced, understanding, and accommodating to the needs of their significant others. You need to think about what you have that is beyond the looks. Just to make another point, being attractive doesn't keep the relationship going. You have to be able to carry on a conversation, and this is usually the harder part.
Common interests always help. Think about what you enjoy doing, and see if any of them overlap with common white guy hobbies. Most white people are heavily into sports. Do you follow Tom Brady trial? Did you know football preseason started? How is your home baseball team doing? Are you aware that there is a record number of no-hitters in this season? Do you play golf or tennis? Do you know who just won the PGA championship for the first time in his life? Do you know who won the latest Open? BTW, this is not just a dating tip, you should know this for your personal friendship or business relationships.
The bottom line is, if you want to date a white guy, you need to let him know you are no different than other white guys.
