There's the 1974 sequel The Nine Lives of Fritz the Cat. Director Ralph Bakshi was well-known for his other adult cartoon films, such as Heavy Traffic (1973) and the ill-fated Coonskin (1975). Heavy Traffic was originally released as an X-rated animated film, but was edited down to an R rating for a re-release effort.
Japan's Mushi Productions released Kureopatra (Cleopatra: Queen Of Sex) in 1970. It's the story of Cleopatra, told through a series of sexual romps with Julius Caesar and other Romans. This has been credited as the first animated film to receive an "X" rating in the United States, although The Nine Lives of Fritz the Cat has laid claim to that title.
Also from Mushi Productions was 1969's Senya Ichiya Monogatari (Arabian Nights). Erotic elements deleted from many modern versions of the Arabian Nights were included in this film. Reportedly, a 100-minute English-dubbed version was made for foreign distribution. This lacked several scenes, including one of sex between Badli and a crocodile, and another involving a lesbian princess.
Cartoonist Picha's works led to several adult cartoon movies: Tarzoon, la Honte de la Jungle (Shame of the Jungle; 1975), Le Chainon Manquant (B.C. Rock; 1980) and Le Big Bang (The Big Bang; 1987).
The British Board of Film Censors cut Le Big Bang by 10 seconds to remove a sequence in which an animated version of God appeared to be having sex and then uttered an expletive.

Halas and Batchelor Cartoon Films' Animal Farm (1954) was the first feature-length entertainment cartoon made in Great Britain. It was also the first animated feature produced for an adult audience.
Based on George Orwell's political fable which examines allegorically the illusion and disillusion of a Utopian society, it "was the first film to use animation in a less than charming fashion," according to the Educational Media Collection of the University of Washington: "Theatre audiences...could not believe that a cartoon could contain serious messages and painful scenes."
Because of the violence content (much is implied, and not shown), as well as the mature theme of the storytelling, this cartoon was given an "X" certificate (no one under 18 admitted) by the British Board of Film Censors when first released in Britain. The rating was later changed to "U" for "Universal," the equivalent of a "G" in the U.S.
Although it is rated PG, I really don't think Bakshi's"Wizards" is a children's movie by any means. (Mind you I haven't actually seen it, just a piece or too)
Also by Picha is a 2007 adult movie entitled "Blanche-Neige, la suite" That's Snow White: The Sequel in English. Basically it's a raunchy continuation of Snow White with a bunch of other fairy tale characters thrown in for good measure.
Don't forget "Once Upon a Girl" an X rated film from 1976 either.
Finally, I've heard of an Italian film from 1973 entitled "Il nano e la Strega" "The Dwarf and the Witch"--it's English title is "King Dick." The plot is as follows: Little Dick, the well-endowed dwarf servant of Master Limpcock is being pursued Nymphomania, an ugly witch who must have 69 orgasms to turn herself beautiful again.
