People keep repeating 'no one is forcing you'. This is a technicality, yes, sure, you can just say no.
To all of them. At the same time. All of them are trying to bang you early through the game during the same scene. You can say no, that doesn't make it any less weird.
You can say no, but you are still exposed to their weird advances and flirting with each other. To clarify, I don't mind romances in the game, I very much enjoy them, specially if they're well developed as a slow burn. I tested every romance scene in my playthrough because I was curious to see how it would unfold. And it feels weird and unnatural.
Hell, I was just trying to be friendly with Shadowheart, trying to make some girl friendship bond, I ended up triggering the romance scene even though I had no intentions of romancing a female. I rolled with it.
P.S: Still weird.

The comparison to some Manson Family-esque sex cult really isn't terribly far from the reality in that scene. There is something incredibly tone deaf about celebrating a small scale genocide with a potential orgy.
