Probably but maybe not :p
Koreaboos are absolutely obsessed with Korean culture. Asian men could be a preference, unless you’re deliberately dating them because you “like their culture” and not their person ; that’s borderline fetishization.
No, I don't think that you are a koreaboo, you just like Asian type of men and that's all and absolutely okay. I also think that you may try using this website here to try to find someone online. Probably you will meet your love there, who knows! Just visit that website to get more information about everything.
