Season 1 has nudity in episodes 2, 4, and 6.... Season 2 has nudity in episode 7.... Season 3 has nudity in episode 1.... There are other scenes of intimacy without nudity in other episodes, but the ones listed were most revealing (including bare breasts, butts, thrusting, etc).

Male and female butt nudity in a few episodes.

A prostitute is seen topless with a customer in season 1 (think it was episode 2)

A couple have sex. Though the scene is dimly lit with shadows obscuring graphic detail, the woman is visibly nude and her buttocks and breasts visible.

Bare breasts of a prostitute is seen in the background as two men fight in what appears to be a dormitory of sorts.

Several scenes throughout the series contain fairly graphic bedroom scenes (approximately 5 episodes over span of 3 season) (with nudity in approximately 3 episodes, while the other 2 show thrusting or kissing but while covered by sheets etc and sexual moaning)

Violence and murder, sometimes senseless.

A beaten up prostitute reveals to a woman that her husband has been sleeping with whores..... That man is shown being beat up later - the wife refuses to leave on supposed Biblical grounds (although the Bible clearly states in Matthew that sexual immorality is grounds for divorce permitted by God)

"Fuck" is said frequently

Blasphemy in several episodes (GD and JC)

Drinking alcohol is seen in most episodes.

One guy is drinking alcohol and another is smoking a cigar in the opening scene.
