repressive societies breed cuckold fetishists because the state/society at large is psychologically cucking them irl

restrictive laws go up
so does bizarre humiliation fetishes and cuckoldry.

Also with guys, simply "losing" at something lowers testosterone significantly, cuckoldry (if you are not the one cucking someone else) literally lowers testosterone because you are putting yourself mentally in the role of a loser.
Now imagine a society which is fundamentally structured around mentally and physically cucking you, people internalize this, they fetishize it, it becomes a sexuality whether theyre aware of it or not.
Hormones effect sexual preference, for men AND women.
