There's a small amount of passionate kissing. A man and woman are seen sneaking off to a hotel room, implicitly to have sex.
No sex, only references (lots of references).
Male nudity - Barman strips completely to underpants in the toilets and points to his genital area.
The film contains a fair amount of verbal references to sexual activities, including different sexual positions and oral sex. In some of the scenes, the verbal references are coupled with some lewd hand gestures by the characters, albeit in a comedic context.
