I think you're forgetting about culture here. A lot of these authors come from places where homosexuality is not accepted, and getting married can even help you climb the ladder in business.
it shouldn't really matter if it's accepted in your culture or not. if you are going to write about it and make it your art, you need to do your research.
"Do your research???" The culture and location of the story literally influence how you portray these topics? Maybe you need to do your research?
it's fine if a character thinks/ says such a thing if it is apparent with their cultural background, but it should have been taken with a grain of salt. for example, it is written as though saying/ thinking such a thing is supposed to be enticing/ turn the reader on instead of doing what it actually does (offend the reader).
there are other instances in manhwas that have said similar things where certain parts of a man self-lubricate, they say certain things that are not socially-aware. it reflects bad research.
so agree to disagree
It is not written as if it should be enticing, it clearly was done to show a level of insecurity. To compare an insecurity that is very real, especially in Asian cultures to men assuming self lubrication is a thing is just silly.
Saying "you'd probably be happier if I were a woman" IS socially aware because if they were a woman, a bunch of social stigma and stress could be avoided.
This trope is my least favourite one lol. Don't get me wrong, this comic is super cute and i like it but I always hate seeing this 'I'm sorry I'm not a woman :(' stuff in bl. Especially when there's no indication the characters ever identified as straight. It's one of the things that make it clear the person writing doesn't know much about irl gay relationships.
