Now I want the ISU to bring back same sex pairs, which I believe used to be a thing back in the nineteenth century.
To the best of my knowledge:
For most of the 19th century, figure skating was either not competitive or not centrally organized. The ISU was formed in 1892.
Most of the structured skating was focused on edge patterns that became codified as school figures.
In England especially there was something called
combined skating that involved multiple skaters performing the same moves in symmetrical patterns. Most skaters at the time were men, and so most of these groups of two or more skaters would have been all male.
Here's a related picture from the continent I just found:

Also in that era, there were Jackson Haines and (male) his Viennese disciples who sometimes performed show programs as duets and otherwise developed much of what eventually became freeskating.
And Haines and the Viennese also were instrumental in developing means of waltzing on ice, the beginnings of ice dancing. Skating in close holds was always for male-female couples to my knowledge.
As far as I know pair skating moves like lifts and death spirals were developed in the early 20th century by male-female teams.
In show skating, any kind of pairing might happen depending who was available.
Similar pairs were a thing when I was a kid. I can't remember if ISI or USFSA had them (or both).
Probably both, although the names might be different.
I remember the term "similar pairs" from when I was a kid involved with USFSA. I remember seeing two older girls practicing a show program to the Beatles' "Come Together" and when the lyrics said "come together" they came together and did a pair spin.
They currently offer duets as part of the theatrical skating/showcase track, which often are same sex.

I see that
ISI currently has events called "Couples" Similar/Mixed and also Pairs.
According to the
test requirements it looks like couples programs would be all side-by-side skating and the pair programs do include some pair moves but not many lifts.
What athletic competitive male-male and female-female pair skating might look like if the ISU or other organization were to offer such events might make a good discussion topic for another thread.
