I remember in the 90s the most head-in-the-sky cultural analysts were like “with the mainstreaming of homosexual relationships, maybe straight couples will come to pick up some gay relationship norms, like the lack of an expectation of sexual exclusivity!”

And I got the sense that was considered silver linings bait for horny straight allies, but looking around at the absolute explosion in idioms for straight nonmonogamy – “cucking”, “sharing”, “passing around”, “free use” – to say nothing of the whole “poly” thing, that was absolutely correct, wasn’t it?
