Sex represented the humanity, love, and creativity that was being quashed by the authoritarian government,

Yeah, see, that's not how the protag's mindset read to me. He seems almost entirely complacent about the other aspects of his and everyone else's oppression. He even scoffs at the rumors of rebellions and mocks those who would try. The one thing he cares about is his lack of sex.

He very much read as a sexually frustrated incel type from the very beginning, lamenting that he couldn't just sleep with whomever he wanted, not for love, but for passion and lust. Hell, doesn't he have a rape and murder fantasy over some woman (Is it the girl he ends up sleeping with? I cant recall). Like, he's absolutely a piece of shit. But, grain of salt, maybe I'm remembering that wrong. I cant recall a ton of details. So, I'll give him the benefit of the doubt.

Again, passion and lust are fine. I just couldn't give a shit about your lust when the world is a machine of lies and control. It's far too petty a concern. Their rebellion was far too self-centered, personal and base to be compelling to me. They are entirely apathetic to Big Brother's control over everything, even one's own thoughts, except where it affects themselves and what they personally care about. They will sneak around to sleep together, consume smuggled luxuries, but then do absolutely nothing to benefit anyone else around them. I just dont care about people like that or want to put myself in their minds. I find it distasteful.
