Karkat actually is quiet during sex, or he's whiny and whimpery; it seems concerning at first, but the fact that he spouts out whines, whimpers, and other such silent noises during it all and even much more at climax, it's actually quite enjoyable.
If you get him real good, however, he can be a little louder if you'd like~
He's like this whether or not he's top or bottom, dom or sub, but there's a few other headcanons that might end up coinciding with this, but that depends on what you guys like.
