All the Loving Couples (1969)
One neighborhood, three couples, and six sexual pecadillos. One guy can't be satisfied, no matter how often his wife gives it up. Next door, the husband is so dis-interested that his wife has to take care of her own needs with a vibrator. Next door to them...well, you get the idea. Finally all three couples get together and the chemistry turns out to be just right!
