The uncomfortable reality is that boys are perpetually in competition with fully-grown men for females of any age from the beginning, girls their own age not excepted. While this phenomenon is usually swept under the rug in the name of propriety for all parties involved, girls in their teens have always received a constant barrage of suitors ages 13-100. The fact that race is a factor is just one more sordid reality we shouldn't be too surprised about. If grown Asian women are so biased toward White men that they will date White dregs over Asian winners, why wouldn't younger Asian girls (who will be the same women in a few years' time)? Perhaps even more so, as younger girls have less filter: they haven't learned and practiced decorum and optics as much.
Just never doubt that this torrent of interest from men to women isn't aligned with women's interests. Women have no loyalty to any group, age or nation or race — they behave exactly like objects and property and money, giving more of themselves to any man who already has abundance, and taking away of themselves from any man less fortunate.
