Because traditionally in the art of that region- china, Korea, Japan - they used to draw huge dicks. Just smth from google
In ancient Japanese art, notably the genre of erotic woodblock prints known as shunga (浮世絵, "spring pictures"), the depiction of oversized penises was highly prevalent. Exaggerated genitalia were a staple of these explicit yet often humorous drawings.
Key elements of these depictions include:
Visual Exaggeration: Artists frequently drew male—and female—genitalia to absurd proportions. Scholars believe this was done to maximize visual impact, ensure clarity within compact print sizes, and heighten the satirical or fantastical nature of the art.
The Kachi-e Tradition: Massive penises were prominently featured in kachi-e (phallic contest) handscrolls. These ancient and medieval drawings humorously depicted men engaging in surreal contests, sometimes rivaling disembodied "farting battles" for visual dominance.
Cultural Significance: While these images were undeniably created for sexual fantasy, they were also viewed with a sense of humor and parody. Penises were occasionally depicted in satirical social commentaries or parodies of religious events.
Artistic Ideal: The highly detailed members in shunga were often depicted as uncircumcised, deeply veined, and vibrant in color.
So manhwa authors just follow this tradition here.
Thanks Chat Gpt? ;) more seriously it s interesting. My theory is just that there must be a weird belief that the bigger it is the better the sex is or just that author believe the audiences wants to see big ass dick, but when that big I find it to be less immersive. Anyway my two cent on this lol.
