From Real Clear Science:
Not only are bonobos liberal in their lovemaking, they also aren’t shy about requesting it. Researchers report in the journal Scientific Reports that wild female bonobos will make blatant gestures asking for genital-on-genital rubbing. Subtlety is not their specialty. The two moves the scientists observed were foot-pointing, in which the female used her foot to point at her genitals, and the “hip shimmy,” in which she wiggled her genitals to mimic rubbing. Some 83% of the time, another female responded, giving the signaller exactly what she wanted. More.
Everything would be simpler if we were bonobos.
But try suing a bonobo for chimp support.
No wonder they are an endangered species.
