In a brief scene, a man and woman are shown passionately kissing and eventually taking off each other's clothes as they engage in sexual intercourse. Thrusting and moaning is present.
Throughout the show there are a myriad of sexual references and jokes, some more explicit than others.
A man is seen from behind unzipping his pants and masturbating on a window wall, he is later seen wiping the semen off in a returning scene, leaving a small smudge.
It is implied that a man posted a picture of his anus on the internet. A brief glimpse of it can actually be seen but it's on a computer and the screen is slightly turned so it can be very easy to miss.
Two scenes show a man urinating on a rug.
A man puts a vibrating phone near a woman's clothed crotch and they kiss.
A woman unzips her pants and shoves a man's hand into her crotch, he starts pleasuring her but the scene cuts before anything happens. Sex is implied.
While on the phone with a colleague, a man starts masturbating and breathing heavily on the phone's microphone as she continues to laboriously insult and belittle him.
Many scenes show couples kissing and making out ardently, and there are several implications of sex and sexual acts, but only a few sex scenes shown throughout the entire series.
The sexual content in this show can be quite strong, especially in the first two seasons, with explicit dialogue & sexual banter.
Bare male buttocks are shown comedically throughout. This isn't meant to be sexual but it is prolonged in a couple instances.
