There are no rules.
You can do anything you want.
That said, I assume that not all the guests who come to my home are equally comfortable with my art, and I have no reason to want to make them uncomfortable. They are my guests. So I make a distinction between public and private spaces.
Private spaces are bedrooms, bathrooms, office and other work spaces where a casual guest is not expected to frequent (if they need to use the bathroom, they’re on their own). In these spaces anything goes.
In public spaces, I usually hang fewer, smaller, more abstract pieces. You might make an entirely different decision.
