Couple talks about the husband masturbating. Another couple also talks about the same, at a separate point in the movie, discussing how it is unhelpful as they are trying to conceive.
At least 5 scenes where lots of cleavage is seen.
Breasts are fully visible in 3 scenes, and partly visible with nipple in at least two others. Most of the breast nudity is in scenes with one specific couple, who are quite one-dimensional (all dialogue is about sex - with a slight mention of basketball once). At its most graphic point this couple is seen having sex in a shower cubicle, towards the end of the film, when the woman turns to face the (clear) wall of the shower (and the camera), and the man thrusts from behind.
A woman touches a woman intimately, running her hand over her clothed upper body. The woman being touched tells her to go further down, until she is at her crotch (this is just off-screen). She then says to go further down still, asking for a foot rub. This couple also kiss in several scenes.
A man is thrusting on top of a woman. They're both moaning a lot. All nudity in the scene is covered, except for a close-up that shows the woman's breasts covered in sweat.
Sex scenes, conversations about sex throughout, breasts shown several times, sex toys, etc.
