As an Asian female, I am not at all jealous that you prefer busty Caucasians. It’s great if more Caucasian women prefer Asian men because in the past Asian men have held negative stereotypes, at least in the US. At the same time, stereotypes have worked as a dual-edge sword for Asian women. I hope that the change in ways that Asian men and women are portrayed in the media (e.g., Filthy Rich Asians, etc.) lead to a move away from stereotypes. Tbh I don’t think that jealousy is what you’re encountering, rather some might be put off by your false sense of grandeur.
