bonobo clitorises larger , more externalized in mammals; while weight of young adolescent female bonobo maybe half of human teenager, has clitoris 3 times bigger human equivalent, , visible enough waggle unmistakably walks . in scientific literature, female–female behavior of bonobos pressing genitals referred genito-genital (gg) rubbing, non-human analogue of tribadism, engaged in human females. sexual activity happens within immediate female bonobo community , outside of it. ethologist jonathan balcombe stated female bonobos rub clitorises rapidly ten twenty seconds, , behavior, may repeated in rapid succession, accompanied grinding, shrieking, , clitoral engorgement ; added estimated engage in practice once every 2 hours on average. because bonobos copulate face-to-face, evolutionary biologist marlene zuk has suggested position of clitoris in bonobos , other primates has evolved maximize stimulation during sexual intercourse . on other hand, frequency of face-to-face mating observed in zoos , sanctuaries not reflected in wild, , may artifact of captivity. position of clitoris may alternatively permit gg-rubbings, has been hypothesized function means female bonobos evaluate intrasocial relationships.
