Mild implied sex without nudity.

A young girl kissing/making out with an older man in a car.

Occasional brief kissing. The most nudity occurs in Season 3 where an older man is briefly shown nude in the shower and you can see his entire naked body side profile (no privates shown) as he sits down in the shower.

Many episodes (particularly at the beginning of the seasons) include a murder (usually off screen). The victims are shown briefly, and it is usually not gory, though sometimes can be a little disturbing depending on how they were murdered. Any on screen violence is usually shown quickly and with little gore.

In Season 4, 5 and 6 the f-word is used occasionally.

Religious swearing such as "Christ", "Jesus" etc appears occasionally.

The strength of language gradually increases with each season.

Mild language in the first 3 seasons. Some infrequent f-words start to appear in the 4th season and as the seasons progress they happen almost every episode ranging 2-15x per episode. Other curse words are more infrequent.

Occasional alcohol, including minors. Drugs and drug trafficking are sometimes part of the stories.
