Many people are apparently nude, but in most cases no private parts are seen except quite a few men's butts. There is one fleeting view of male full frontal, and a slightly longer view of a woman's breasts. Most men are wearing briefs, most women, bras and panties.
It's an orgy; lots of sex is shown, heavier on male gay interactions, with considerably less straight and almost no lesbian activity. There are three-ways, a virgin, people who aren't certain how much they wish to participate, and people who try to join in when they aren't welcome. There's no rape, and no coercion other than pleading. Infidelity and betrayal are points in some of the 7 or so plot lines.
