Understandable. Although I imagine it's because in some parts of particular Asian culture, there are some men who are focused on beauty as much as women are. And a lot of Asian men in general are a little more on the petite side. Korean peoples are especially focused on skin care and their facial appearance, I mean just look at some of the boy bands that pop outta there. But i TOTALLY get where youre coming from
It's cisheteronormative culture.
These women authors can't fathom that two muscular and dominant men with big cocks can be bottom and versatile.
They always gotta make one of the guys the "woman" in the relationship,and go figure they make the "girl" be a virgin, naive, and always forgiving of their abusers.
Such projection of their own gender experiences.
I don't mean to be intruding but I kinda feel disgusted by some BL yoai manhwas. They seem to illustrate the ukes with extremely petite facial and body structures. Every time I see their genitals and their form they look like underage individuals, which really throws me off. ヽ(`Д´)ノ
