Some scenes in underwear male and female, in about every 3rd episode.

A few episodes with scenes where sex is implied, but the scenes end right after the situation is implied. Nothing explicit, nothing is shown, only underwear.

Beginning in Season 5 Episode 5, the words 'fuck and shit' infrequently.

Season 5 includes religious epithets (Jesus) and other swearing.

There is not much cussing before season 5
