There are many jokes about a man's sexuality. Mostly in one episode, but it is also joked about in others. not graphic
This show contains sexual jokes in every episode, and it also contains nudity, but it is always censored and very infrequent.
In one of the earlier seasons, Michael and Ryan go to a sex toy store, but no explicit images are shown due to them being censored. However, Michael laughs and Ryan says that's all he has been doing the whole time.
Some implied sex though it is never shown outright.
One episode deals with a watermark put on the paper of a cartoon duck and mouse having anal sex and it is shown several times.
In many episodes, Michael's main joke is "that's what she said".
In one episode, Jan gets a boob job and her cleavage is not shown, but she is wearing a very low-cut shirt.
Lots of sexual references including references to sex, gays, lesbians, 69 position, oral sex, anal sex, masturbation, circumcision, STDs, handjobs and strip clubs.
In Peacock's Superfan episodes collection, a deleted scene shows a dumpster moving around a lot with Kelly and Ryan moaning. This is heavily impling sex, but nothing is actually shown onscreen.
Ryan and Kelly passionately make out in various scenes throughout the show.
Michael shows some sexual attraction towards the temp, Ryan. It is played for comedy, but it can be uncomfortable as it is the boss showing unrequited affection towards a subordinate.
Infrequent comments about Pam's breasts.
At a bachelor party in a restaurant or brothel, a stripper in a skimpy outfit sits on Dwight's lap and writhes around, making suggestive comments to him. He remains oblivious that she is in fact, a stripper, and not his waiter.
Bob and Phyllis are heard having sex in a closet. Very brief.
It is said that Phyllis was flashed by a man in a parking lot. In that episode, there are several mentions of penises.
Multiple instances of male topless nudity. Also, there are men in underwear.
Characters play desert island games, such as "who would you do". Multiple men quickly say Pam's name, clearly making her uncomfortable. When Michael finds out what they are playing, he says "I play this game all the time at home when I'm falling asleep!" then he says "Well I would definitely have sex with Ryan!"
A woman is shown to be wearing a dress that is pulled up fairly high. She is asked to pull it down a bit, and one of her breasts is exposed, with a male employee stating that "her boob is out". She then pulls it back up, revealing her vagina, as she is not wearing panties. Then, she bends over, showing her buttocks to her coworkers, but all of the nudity is censored and it is played for laughs.
In one episode, Michael brings in a suggestive doll.
There's sexual graphic content throughout the series.
There is some mentioning of nudity though the nudity is always implied and rare if ever shown. There are also references to sexual orientation and humor around character's sexual orientation, and additionally, there are several sexual jokes throughout the show. However, references to sex, sexuality, and nudity are never explicit.
Meredith flashes Michael for about two seconds, then he runs away, implying that she is drunk. Only her back is shown.
Jim and Michael go to hooters, and women are shown in scantily clad outfits.
Michael kisses Oscar in a conference room, and also, this episode has a LOT of gay humor.
A stripper is hired in a warehouse. Fully clothed, she sits on a man's lap, starts dancing a little bit, and then rips off her shirt to reveal her bra and midriff, which can be seen for about four to five seconds. Not a very suggestive scene, and is meant to be humorous in an awkward way.
Michael fondles Jan's clothed breasts for about 10 seconds. He also mentions wanting to squeeze and "motorboat" them at one point (he merely makes a motorboating sound effect).
Two characters come close to basically having a legal prostitution-like contract. No sexual action is shown.
A married couple worries about whether or not their baby is breastfeeding correctly. A lactation consultant comes in and puts his hand up the wife's shirt to make sure nothing is wrong. This makes the husband uncomfortable since the consultant is a male. Mainly comedic.
Andy is a sexual education instructor. In the conference room, there are many lines of dialogue about STDs, impotence, and erections in this episode.
Three men prepare to skinny dip and their backsides are seen, although their buttocks are all blurred.
Andy fails to perform sexually and there is an entire office meeting discussing impotence. This includes references to "satisfaction" and ejaculation and is pretty explicit, even in comparison to Todd Packer episodes.
An instance of Dwight's entire naked body is shown onscreen with his penis blurred out.
The F-word is about to be used with its sexual meaning but the character stops himself saying "you (two) were fuu-uuhhh ahhh!"
One man says "Let's talk about penis diseases, how about you." He points towards a woman and she says "I don't have a penis, I have a vagina." This is meant for laughs.
Although sexual references to oral or anal sex are never explicitly stated, and they are usually somewhat cryptic and subtle double-entendre references, there is one episode in which Michael explicitly talks about oral sex as having a "penis in your mouth." This is perhaps the most explicitly-stated crude content in the show.
Overall, while there is a lot of sexual content in this show, all of the nudity is suggested and covered by censor techniques. Also, a lot of the sexual jokes are not supposed to be accepted, and the characters are often appalled at one character in particular's language.
