Infants in bonobo societies are often involved in sexual behaviour. [78] Immature male bonobos have been recorded initiating genital play with both adolescent and mature female bonobos. Copulation-like contact between immature bonobo males and mature female bonobos increases with age and continues until the male bonobo has reached juvenile age.
Unlike chimpanzees, where any male can coerce a female into mating with him, female bonobos enjoy greater sexual preferences and can rebuff undesirable males, an advantage of female-female bonding, and actively seek out higher-ranking males. [86] Bonobo party size tends to vary because the groups exhibit a fission–fusion pattern. A community ...
Two male bonobos. Bonobos form a matriarchal society, unusual among apes. They are fully bisexual: both males and females engage in hetero- and homosexual behavior, being noted for female–female sex in particular, including between juveniles and adults. [103] Roughly 60% of all bonobo sexual activity occurs between two or more females.
In bonobos, the amount of promiscuity is particularly striking because bonobos use sex to alleviate social conflict as well as to reproduce. [28] This mutual promiscuity is the approach most commonly used by spawning animals, and is perhaps the "original fish mating system."
Males of certain species have evolved mating behaviors in which they forcefully attempt to mate with and inseminate females, often employing grasping techniques. These male grasping devices exist to increase the duration of copulation and restrict females from mating with other males. They are in some ways a form of mate guarding. While some ...
The position of swellings can heavily influence the location of male focus during courtship, and of eventual penetrance. Among chimpanzees, bonobos, baboons, and many Old World monkey species, it is common for swellings to concentrate in the perineal, perianal, and coccygeal regions, rather than more ventrally in the area of the vulva.

Capuchin monkey. A study at Yale–New Haven Hospital trained capuchin monkeys to use silver discs as money in order to study their economic behavior. The discs could be exchanged by the monkeys for various treats. During one isolated incident, a researcher observed what appeared to be a monkey exchanging a disc for sex. The monkey that was ...
Two bonobos mating. The pelvic thrust is used during copulation by many species of mammals, [1] [2] [3] including humans, [4] or for other sexual activities (such as non-penetrative sex). In 2007, German scientists noted that female monkeys could increase the vigor and number of pelvic thrusts made by the male by shouting during intercourse. [5]
