I'm not a "bro", let's start with that and you don't have to explain human anatomy to me - I get it, hence my inital comment.
Also I'm not insistent on it - that's the connotation the webtoon is giving, and a lot of other yaoi/BL works do the same and have been for decades (when it is clearly incorrect). If you haven't read them to then have the same opinion as mine? Good for you, I wish I could say the same about me.
Now, I have no intention of getting into this conversation any further - I honestly have better things to do...like work and my own life.
"Look at how wet you are." That made laugh. Like dude...unless you used lube if he's wet from his behind then you better take him to the doctor.
Sometimes I need to remind myself that logic should be thrown out the window when reading BL/Yaoi, because those authors don't even do basic research.
