Implied sex (no actual sex is shown) and no real nudity. To save you a lot of reading below: sexual references and women cleavages.
There is a lot of sexual innuendo and references to sex (including homosexual sex): a man mistakenly thinks another man is propositioning him and is interested, a man shows interest in another man, a man plays a game with a woman in a bathtub and it is implied that he uses his hand to satisfy her, a man loads a gun and expresses his arousal.
There's a really quick scene that shows a man and woman presumably having sex on an elevator with the woman moaning and calling the man's name.
A man throws himself on a woman on a couch and kisses her; she shows interest for a moment and then throws him onto the floor.
There is a scene showing the voluptuous Tracey wearing a red top that is both tight-fitting and cleavage-revealing, she was sensually leaning over Max to massage him.
A man does a dance in his boxer shorts and tuxedo jacket and then jumps into bed with a woman.
A man and woman are shown in bed presumably after making love; we see the woman's bare shoulders and they kiss a couple of times.
There are several other scenes showing couples kissing and flirting with each other.
A man looks at a Playboy magazine in the bathroom while Tracey (referred to as Miss September) is in a tub full of bubbles; we see her bare shoulders and knees popping out through the bubbles.
A naked Tracey is seen fresh out of a bathtub with bare soggy shoulders and the rest of her body away from the camera; she exits the bathroom to confront Kevin until Max tells her to cover herself with a towel.
A woman bends over and a man ogles her big butt.
A woman is seen in a halter dress exposing some cleavage, a woman is seen in a bathrobe and skimpy nightie and many women are seen in evening gowns with bare shoulders, backs and cleavage.
