>>713551095at least japan seems to have a diverse range of degeneracy, Koreans though, they just love cuck shit, even the "wholesome" korean shit that I have seen always involve some kind of ego stroking where the girls is like "omg you're so chadly and your dick is so le big".
I once got shilled this doujin manhwa called sexercise and the art was hot but the whole plot revolved around the MC having a huge dick and secretly amazing genetics for bodybuilding while the main love interest's boyfriend was cartoonishly evil and had a small dick so the story would ironically enough put down the villain guy who'd have a big cock in normal manhwas for having a small penis in this case and it would lift up the nice guy protag (who'd usually be the cuck) by showing how his cock was huge and muscles so strong.
