There are constant sex jokes almost everywhere and a lot of the characters are of sexual nature; for example, there's a Satanist that's introduced later who drinks his own sperm. He only drinks it twice on screen, but mostly just shows the jar(s).
In one of the episodes it's explained how gentles work in heaven and hell; in heaven they're removed but in hell they're used as a torture method. But it's neither process is shown and is said as a side gag/world-building.
Violence & Gore
Moderate
The gore mainly comes from purgatory's clients. From a serial killer who wears his victims skins like lether face to a guy who has his skin ripped off completely, getting blood all over the office.
There's no straight up acts of violence. If anything the details are almost cut completely, and all the audience sees is the aftermath via body.
Profanity
Severe
The f word, the s word, and g*d is said frequently.
The f and s word and g*d is said frequently.
Swears and profanities of all kinds are thrown around. Fuck, of course, is the most uttered of all of them.
