We see a woman in the shower with her bare back and parts of her breast
A man and a woman talk in detail about the differences between the male and female sex organs and debate which is the ultimate sex organ.
A woman kisses a man, pinches his nipple, invites him to perform cunnilingus on her, they kiss, he lies on top of her, and then she rolls him over and climbs on top of him; she takes his shirt off, they passionately kiss and she thrusts her hips rhythmically. (tongue visible)
A man takes off his shirt and flexes in front of a mirror, and a man takes off his robe and stretches in front of a woman.
When Larry tells his mom that Ricki is a lesbian, his mom says she can tell Ricki has been with guys before. She then adds that she (the mom) used to be quite experimental in her youth.
When wanting to speak to Ricki, Louis tells Larry, "Put the clam-licker on."
Larry's mom shows abundant cleavage and we see part of her butt cheek (and that she's wearing a thong) as Larry gives her a shot in her rear.
We see various young women in bikinis, first from a distance and then up close where they show varying amounts of skin (some in skimpy bikinis).
There is a woman in a sports bra (that shows cleavage) and small and tight shorts as she exercises and does various stretches (some of them sexually suggestive considering the context of the following discussion).
