Annelise Meineche – Uden en trævl aka Without a Stitch (1968)

When a high-school girl complains of her inability to reach sexual
climax, her doctor suggests that she keep a diary of her sexual
encounters. She does just that and soon finds herself caught up in
a sexual merry-go-round that includes making a hardcore porno film
in Sweden, an escapade with a German sadist and a lesbian
encounter.

Radley Metzger – The Lickerish Quartet (1970)

Synopsis :
In their castle, a wealthy couple (Frank Wolff and Erika Remberg) watch a blue movie with their adult son, played by Paolo Turco. Later that evening at a local carnival, they spot a woman (Silvana Venturelli) who appears to be one of the performers in the film and decide to take her home with them. Although a subsequent viewing of the film calls the woman's identity into question, their house guest quickly succeeds in seducing the various members of the family, resulting in the revelation of certain facts, fears and desires.

Richard Franklin - The Oral Generation (1970)

Quote:
Presented by “Family Studies Institute” THE ORAL GENERATION purports to be the first sexual instruction film aimed at liberated women; although it’s focus is of course on how a woman can please a man (or how a woman can please a woman with a man watching) in a non-conventional manner. The narration describes the greater availability of literature on sexuality aimed at female readers (although what we are shown on-camera are the usual texts from Kinsey to Krafft-Ebing to "The Joy of Sex" and "The Sensuous Woman" as well as the usual porn magazines) as well as female-focused films (during a montage of 42nd Street porn theater marquees). The oral sex interludes intercut with this academic discussion take the form of anecdotes by wives surprising their husbands in the showers or role-playing as their husbands secretaries (the only interlude that is remotely arousing in its rhythmic and escalating intercutting). There's also a bizarre vignette involving a black samurai and a ménage a trois. Credits are non-existent for this one, but one of the performers appears to be Tina Russell (the 1970 date comes from Vinegar Syndrome's back cover).
