Wrong. Bonobos (similar to chimps, also called pygmy chimps sometimes) will "do it" in different positions, even face to face. Often the female picks the position she wants and even has sex with another female if she feels like it - lesbian monkeys, wohoo
I heard of dolphins masturbating using corals.
And I have read about a female chimp in a research project that would actually masturbate while looking at Playgirl magazine
