The story revolves around visits to a swingers club. There's a lot of sex scenes. In a few of them women's breasts and men's butts are visible, but mostly bras are worn. Some but not pervasive toplessness of characters in the background. A couple of times hands are seen on women's bra-covered breasts or men's underpants caressing the groin.
There's a lot of discussion of relationships, both sexual and romantic; sexual dis/satisfaction; and a couple of scenes with characters tied up for BDSM activities.
Sexual interaction is shown between straight folks and female and male gay folks.
