In season 2 there is a kissing scene.

In one episode a girl grabs a guys waist from behind, it's obvious she's touching his privates.

Two men are shown in their boxers. Another scene a woman gives birth but nothing is shown.

A man and woman wake up in bed and their bare shoulders are seen with a blanket over them.

A man attempts to rape a woman but she fights him off

Some of the episodes contain deaths. A man is shot a few times, a woman's finger is shown cut off, a girl is seen with blood all around her implying she tried to kill herself. There is also lots of hostility between characters as the series goes on, and there are many fist fights.

Various people die from a mysterious virus, and many of the deaths are shown on screen. They cough up blood, and collapse.

Damn, Hell, Ass, Shit.
