So as I’m a health student I can actually explain. We live in a different dimension as manhwa. As you see our intestines or front girl are not straight u know idk girls but like intestines not straight, also notice that mouth is not straight cause lungs and stomac and all u know a lot is happening, so my theory is, people in manhwa have a straight one hole like pipe going through mouth stomac and ass, cause like, when you see them inside going full power deep af, it’s straight always, and no, 20 inch on our inside is not straight for sure, so yeh their bodies are ready to take all of it, they made for sex. That’s my theory <3 also stomac existes cause food and alcohol is a key for going hangout at one another’s home, so yeh bodies ready for flirt and sex.

I get what you are saying, in some yaois it is indeed straight but if seen some with a curve, you know even in real life dicks like this can be swallowed whole , i mean docks like this exists in real life mostly with surgery or real gifted but anyways, i think some people don't have the gag reflex if that's what is called. If i remember correctly the bottom from love stage had it. And cause it's fictional of course they wouldn't make the have the reflex cause it would be a turn off
Ayo new Chapters in the raws came out
