And it was supposed to be kinky and not dark, as Joy comments, then why have it set in Pariah which is established as a fairly hellish place? In addition to probably breaking some sort of record for the sheer amount of sex being depicted at one time, this scene seems to clear up the question of whether the robots at Westworld ever get busy with each other just for funzies; with all the naked bodies in that room, there was definitely some android-on-android action happening.
At the last week, creator Lisa Joy discussed the significance of the show's nude scenes—particularly in Season 1—and promised there would be less in Season 2: I remember going to the Met as a kid and looking at these sculptures of all these forms, and it wasn't licentious, it wasn't sexual, it was just the idea of the human body as art, as perfection, as this mix of muscles and cells that moves and walks and changes and grows.
However, like, at least in Westworld, there was an obvious hierarchy at play.
