Female, Sex, and Bonobo
The bonobo, previously called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee,…
The bonobo is popularly known for its high levels of sexual behavior. Sex functions in conflict appeasement, affection, social status, excitement, and stress reduction. It occurs in virtually all partner combinations and in a variety of positions. This is a factor in the lower levels of aggression seen in the bonobo when compared to the common chimpanzee and other apes. Bonobos are perceived to be matriarchal; females tend to collectively dominate males by forming alliances and use sexuality to control males. A male's rank in the social hierarchy is often determined by his mother's rank.
