I was having a conversation about this. The lifestyle and general exposure that has influenced sexual desire between different races, in this context, Black and white people, has an unfortunate racist history that has led to the lifestyle feeling taboo and overly fetishized. That being said, a lot of white women may indulge in the lifestyle without ever doing the work to unlearn the dangerous and racist ideologies they may have against Black people but that doesn't stop them from seeking sexual pleasure.
