By "pressure" I mostly just mean like them being present for sex involving someone of another gender/someone of another gender being present for their sex life (including, uh, in person?) and mixed gender kisses of characters in same-gender relationships in the orgy scenes. (Including one of a man sharing with Nomi while she kisses Amanita, which Amanita is bi, but surprise!sharing is still uncomfortable.) On its own--yeah, it's temporary, it's experimentation, it's empathy--I like everything you just said! But the "everyone in the cluster will end up pansexual" thing is word of god, and that makes it sort of uncomfortable? There's a couple of monologues about how Sex is Life, I think, and sex is portrayed extremely positively, which can be euphoric to watch, I admit! But then there's this fridge logic about how no one's really allowed to say no to it and when non-cluster partners are around it's voyeuristic. It works out fine because everyone's okay with it and loves it in the end, at least the stuff they know about!

I was pretty okay with Will's bicuriosity, especially since it's not uncommon for "straight" people to have never questioned their orientation, whereas gay people are pretty much guaranteed to have asked themselves, "could I be bi?" at some point.

But also, honestly, if you don't fuss too much about word of god comments and just take what's there on the screen, better and kinder interpretations are certainly possible.
