There are gay dudes, gay women, bi people, there's married gay couples. Players can marry same gender. Everything. None of it is ever portrayed negatively or for comedic effect. It's just there sometimes. You don't have to go out of your way to find it either, you directly encounter a chunk of it on the main quest line.
This game has absolutely zero concern with lgbt content. Anyone that has played this game will not believe myths about official censorship of lgbt content having directly seen for themselves that it's not.
I had not found that dungeon yet.
Top left corner of kaifeng, go into the building, open the trap door inside the building.
There is no associated quest. It's just a hidden sex dungeon with a dude obviously RPing as a kidnapped guy to be ""tortured""
in there. You can absolutely miss it because it's hidden.
