    Allogrooming in Bonin flying foxes has never been observed, hence the male-male genital licking in this species does not seem to be a by-product of allogrooming, but rather a behavior of directly licking the male genital area, independent of allogrooming. The encounters are analogous to heterosexual bouts, one male often extending his trunk along the other's back and pushing forward with his tusks to signify his intention to mount. After aggressive "necking", it is common for two male giraffes to caress and court each other, leading up to mounting and climax. Male elephants, who often live apart from the general herd, often form "companionships", consisting of an older individual and one or sometimes two younger males with sexual behavior being an important part of the social dynamic. Male homosexual behavior occurs both in the wild and in captivity, and it occurs in both adolescent and mature individuals. If two bonobos approach a cardboard box thrown into their enclosure, they will briefly mount each other before playing with the box. Affectionate and playful activities are associated with such relations. Often, strong and lasting friendships result from such pairings. In some troops up to one quarter of the females form such bonds, which vary in duration from a few days to a few weeks.

    She may then proceed to mount the other female, during which the mounting female gently grasps the mounted female's dorsal neck fur in her jaws while thrusting. Such situations lead to squabbles in most other species. Often, strong and lasting friendships result from such pairings. A jealous male might chase another away from a female, after which the two males reunite and engage in scrotal rubbing. Such interactions between males have been found to be more frequent than heterosexual coupling. Male—male genital licking events occur repeatedly several times in the same pair, and reciprocal genital licking also occurs. Males often have erect penises while they are mutually grooming each other. In addition, the oSDN of the female-oriented rams expressed higher levels of aromatase , a substance that converts testosterone to estradiol , a form of estrogen which is believed to facilitate typical male sexual behaviors. Aromatase expression was no different between male-oriented rams and ewes. Allogrooming in Bonin flying foxes has never been observed, hence the male-male genital licking in this species does not seem to be a by-product of allogrooming, but rather a behavior of directly licking the male genital area, independent of allogrooming. Pairings between females are held to be fairly common in captivity but have not been observed in the wild. Bonobo sex often occurs in aggressive contexts totally unrelated to food. Females will form " consortships " characterized by affectionate social and sexual activities. The encounters are analogous to heterosexual bouts, one male often extending his trunk along the other's back and pushing forward with his tusks to signify his intention to mount. Aromatase mRNA levels in the oSDN were significantly greater in female-oriented rams than in ewes, whereas male-oriented rams exhibited intermediate levels of expression. In some troops up to one quarter of the females form such bonds, which vary in duration from a few days to a few weeks. Or after a female hits a juvenile, the latter's mother may lunge at the aggressor, an action that is immediately followed by genital rubbing between the two adults. Unlike heterosexual relations, which are always of a fleeting nature, the relationships between males may last for years. Affectionate and playful activities are associated with such relations. While the homosexual bonding system in bonobos represents the highest frequency of homosexuality known in any primate species, homosexuality has been reported for all great apes a group which includes humans , as well as a number of other primate species. Confrontations between flocks of bottlenose dolphins and the related species Atlantic spotted dolphin will sometimes lead to cross-species homosexual behaviour between the males rather than combat. Homosexual behavior in orangutans is not an artifact of captivity or contact with humans. Both sexes display this form of mutual homosexual grooming and it is more common in males. The Merck Manual of Veterinary Medicine appears to consider homosexuality among sheep as a routine occurrence and an issue to be dealt with as a problem of animal husbandry. If two bonobos approach a cardboard box thrown into their enclosure, they will briefly mount each other before playing with the box. Exclusive homosexuality with mounting and anal penetration in this solitary species serves no apparent adaptive function.

      But bonobos are quite tolerant, perhaps because they use sex to divert attention and to defuse tension. Females will form " consortships " characterized by affectionate social and sexual activities.
