I've also noticed that the idea gets some disdain. Heck, even with the you_people channel on Discord, people just assume that some kind of weird perverted stuff goes on there. (It, in fact, seems to be mostly full of adults complaining about being adults)
And oh, someone did send me a NSFW fanart of Shallan & Vin after seeing this. So, looks like stuff is out there... somewhere.
(PS next time, just for reference, I'm into dudes, so maybe send me that!)
