The earliest porn I ever saw was from the "Black Socks Era" of the 1930s. It, too, was silent but at least it had blackboards with some dialog that would pop up. In the one I recall, the male actor looks up at the camera from his quarry and the line that pops up is: "I believe she WILL!"
At another point, two couples have left their car carrying blankets and are headed for a grove of trees. Then a story board pops up reading; "It's over the hump for a piece of rump!"
Priceless.

That’s great!
There’s a dive bar in Vegas called Dinos that plays old porn on the tvs.  I can never get over how much pubic hair was the norm way back then!

shaving your crotch is a more recent invention.  

 
My dad had some of the old black-socks movies, no sound, because I think they were 8mm.  They might have been 16mm because he had both projectors.   When we were teenagers and the folks were away for a weekend, my brothers and I would pull them out and watch them.  Sometimes, girls we were dating wanted to see them, too, and that led to some good times as a yute.

In the super olden days they had “merkens” which were pubic wigs!  The working girls of the era would shave for hygienic reasons and to get rid of pubic lice, but men expected the bush, so the pubic wig was worn. I have no idea how they would attach such a thing or keep it secure during a vigorous session!!

While I suspect few will bring it up in intro anthropology courses but I would not at all be surprised to find that you can find some type of sexual drawing in caves. Just never gets reported as it would not be PG or PC.

First of all, I do not believe that that 9 minute film is from 1907. I'm no expert, but there are a lot of qualities that seem to be superior to non-porn professional studio silents from the 1910s and 1920s. "High res" (for the day). Not a lot of graininess. Lots of lens changes. Etc.. I'm not buying the 1907 claim.

But there were pornographic, explicit still photos before movies even existed. I would not be surprised if it turns out that Daguerre invented daguerreotypes as a way to coax his girlfriend out of her undies.

What I liked is that the girls were pretty and their nakedness was totally natural. The direction or "plot" must have been, "This scene takes place in the days of the Garden of Eden, before clothing, before there was any shame with nudity. Run around, have fun, be natural. Lights! Camera! And ... ACTION!"
