Non-reproductive sexual behavior consists of sexual activities animals participate in that do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals , recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Observed non-procreative sexual activities include non-copulatory mounting without penetration, or by the female , oral sex, genital stimulation, anal stimulation, interspecies mating, and acts of affection. Lions are known to engage in sex to create bonds and interact with each other. Lions live in a social group known as a pride that consists of 2—18 females and 1—7 males. The females found in these prides were born into the pride. The males enter the pride from other prides.

These apes supposedly have inordinate amounts of sex and never fight. Can this appealing story really be true? Reputation: Bonobos are miniature, sharing, caring chimps, living in hippie communes with no aggression and lots of sex. Reality: Not really.

At a juncture in history during which women are seeking equality with men, science arrives with a belated gift to the feminist movement. Male-biased evolutionary scenarios--Man the Hunter, Man the Toolmaker and so on--are being challenged by the discovery that females play a central, perhaps even dominant, role in the social life of one of our nearest relatives. In the past two decades many strands of knowledge have come together concerning a relatively unknown ape with an unorthodox repertoire of behavior: the bonobo.
