What's Jane Gotta Do With It? (USA 1972)

Lovely natural redhead Clair Dea stars as Jane, a housewife deeply in love with husband Johnny (John Christian), but unable to achieve an orgasm when they make love. It's clearly his fault, as she can get off while masturbating, but his wham/bam approach in bed is unsatisfying to her. She seeks the counsel of her best friend dating back to college, Michelle (ultra-built Martha Strawberry), who suggests vibrator treatment. Michelle brings a huge Sarno-esque massage gadget from her car and treats Jane's clitoris to a workout that is more than satisfactory. Of course, the two women segue to a heated lesbian sex session.
