Tribadism - Among Female Bonobos

Among Female Bonobos

Female-female genital sex is not exclusive to humans. Females of the bonobo species, found in the Democratic Republic of the Congo, also engage in this act, usually known as GG rubbing (genito-genital). "Perhaps the bonobo's most typical sexual pattern, undocumented in any other primate, is genito-genital rubbing (or GG rubbing) between adult females. One female facing another clings with arms and legs to a partner that, standing on both hands and feet, lifts her off the ground."

In bonobos, the clitoris is larger and more externalized than in most mammals. Bonobos rub their clitorises together rapidly for ten to twenty seconds, and this behavior, "which may be repeated in rapid succession, is usually accompanied by grinding, shrieking, and clitoral engorgement". On average, female bonobos engage in genital-genital rubbing "about once every two hours".
