The situational bisexuality that occurs in the prison alone (or, as the characters call it, "gay for the stay," which is another way to avoid naming bisexuality - more on that later) is something that's rarely portrayed in a consensual way. This isn't to say Orange Is the New Black doesn't portray sexuality in compelling ways - it does. Her sexuality is one of the cruxes that power the show (that and, you know, Ruby Rose winking at us). She's a white, upper-middle-class WASP who makes artisanal soaps and terrible decisions. Piper's bisexuality is also the only interesting thing about her (barring the fact that she's in prison).

It's also radical in the complex and entertaining ways it explores race, class, and gender privilege, which is why it's strange that a show so good at presenting diverse characters is also afraid to say the word "bisexual” - especially when, for the first two seasons, one of its central conflicts involves how its main character Piper grapples with her bisexuality. First and foremost, it's a show about women (I mean, whoa, right?).
