Basically, all Moche sex bottles that have been recovered in context come from burials, they're a small minority though, most were acquired through messy huaquero looting.
But from what is known, it seems they allowed sex art in cemeteries but never outside, weird isn't it? The skeleton pots come from burials too, but that’s more in line with what you'd expect, like the one you posted (and sometimes the undead are having sex!).
But stirrup vessels have also been found in domestic contexts, showing signs of use. Many others, though, are pristine because they were never actually used, they were made specifically as grave goods.
