If your qualifications are exposure to bbc, then I’d would have to say white girls have far much more exposure to bbc and are much willing to try bbc than Asian girls are. Not sure why exactly that is, maybe it’s cultural. Asian women tend to seek out white guys more so than white girls seek out black guys. I believe it is the most common interracial pairing in the United States by far. I always joked that if Asian girls eventually find out what their missing in the bbc, white guys are doomed lol.
