I liked the jokey alternate title "Woodworking 101" in this typical Nina Hartley sex-ed video made for the Adam & Eve label, one of the earliest of her dozens of projects in this vein. I haven't seen her companion video on Better Cunnilingus, but obviously it's a necessary one to view.

Standing at a lectern clad in a sexy red body suit, she's the ideal Educator, using slides and illustrations as she gives us a male anatomy lecture and folksy description of how a man's loins work, technical terms included. At the 27-minute mark in the video, a hardcore demonstration is delivered with Alex Sanders as her subject male.

Nina finishes off the show enacting a fantasy scene with Sanders, in which she is an artist and he portrays her nude model. It's explicit, including a tantalizing CFNM interlude, and even a money shot deposited on her breasts. For the intercourse material, safe-sex via a condom is carefully included.

I greatly enjoy these Hartley (and hubby Ernest Greene as collaborator) videos, though I suspect they must seem awfully quaint, a la early '70s White Coaters, to a current audience more interested in vicarious gonzo thrills than perhaps learning something about sexuality.
