I just remembered the first porn video.
Raquel Darrian appeared in movies with her boyfriend (only), who was intact. She didn’t go too far out of her way to demo his foreskin, but she’d pull it over the glans occasionally.
I believe there was a taboo against explicit foreskin action in those days. The (likely circumcised) producers didn’t want their (mostly circumcised) audience to come away traumatized over what they were missing.
