Several scenes referencing sex or showing sex. Frequent sequences with prositituion visible (young girls standing around sketchy areas and on the other hand, brief sex scenes including threesomes with erotic dancing). Some scenes are set in strip clubs.
The main character's partner is a sex addict; this is brought up in conversation a number of times.
A woman's boobs are shown for about three seconds on some surveillance footage. The quality makes the nudity easy to miss.
