The title. Oregon v. Rideout is often listed as the first case of a husband charged with rape of his cohabiting wife. It happened in 1978.

This fact alone is occasionally (more like 200+ times, and to me personally as recently as 2 days ago) mentioned here as some sort of an instant obvious conversation-stopper. It's not obvious to me, because I was taught for 19 years of my training that comparisons are possible only in comparison.

When was the first US case of a woman charged with rape of her cohabiting husband?

My personal Google gave nothing.

Since most people bringing this topic up seem to be either Blue or Purple, I post it as Question for Blue Pill.
