Het lady here, and in my house it's "the other way around." The only one who's ever been banished from the bed is me. In 20+ years, I've never "sent him to the doghouse." Not even when I was super pissed. Just never occurs to me, I guess. A few times I've been too angry to sleep next to him… so I went to the couch (which suuucks). But if he's too angry, I get unceremoniously bounced. ¯\_(ツ)_/¯

I'll be perfectly honest (and he would admit this too), he can be a bit… petty when he's that angry. So yes, that it's dismissive and demeaning and physically uncomfortable is part of the point— of course. If it was just about sleeping alone for a night, he could choose the couch! I can sort of laugh about it (sort of) because it's happened pretty rarely, but yeah, it's kinda mean.

 
More generally…

On top of everything else, I feel like the whole trope just has ages of of gender baggage quietly built into it. There's "men are strong and don't require physical comforts/women are fragile so they do"— so of course he gives up the bed. There's "women are irrational and ruled by emotion"— so sure, maybe she's trippin', but that's what women do amirite? As the rational party he concedes, for the greater good. (C-c-c-combo: maybe she's pregnant or menstruating! In that case all he can do is keep her comfortable and wait for the crazy to pass!) And of course we can't forget "women are the gatekeepers of sex.' Kicking hubby out of bed for the night = denying him your body for the night.

Weirdly, het men flipping the script today actually packs the same punch by tapping into the same baggage. It's the guy saying "I don't care if you're comfortable, I'm not interested in being rational, and you don't get to have this d!"
