Many sexual references. The main theme of this show is sex. Even the title of a few episodes is sex related.

Constant talks about sex and other related stuff. Talk about porn, masturbation, orgasm, breasts etc. A lot of such talk is done in this show.

A man's bare butt is seen in one episode or two.

The main characters are presumably nude, each in one or two scenes in 6-7 episodes while nothing much is shown. Bare back and nothing below the waist. No frontal nudity.

The main characters also lay in bed in many scenes presumably after sex. Some of them talk about sex they just had.

But nothing very explicit. The nudity and the kisses are many-a-times just used for humour.

Some scenes may be a little violent but they are just used for humour. For example - hitting the other person

Mild curses like bitch, bastard, arse, dick, shit etc. are use many times. Several other explicit words referring to body parts are used.

Strong profanity like the F-words are used a little less. Series 1 and 2 do not include F-word. Series 3 includes 2 F-words in 2 different episodes (one in each). And the series finale in Series 4 includes 5 F-bombs and their derivatives.

But in many cases these words are used just for humour.

The main characters are seen in a bar a lot of times drinking alcohol. Drinking at home is also seen.

Not many instances which the kids may find frightening. There might be few which they do but all of them are just for humour.
