The bonobo is a very sexually active species of ape, they engage in homosexual intercourse, as well as pedophilic intercourse. it is part of a bonding activity, and it helps them to come to resolutions.
For example, rather than fighting over a piece of food, they might have sex and then share it after the intercourse. And they do not discriminate. They have sex with the young and the same sex, and the one that is 'receiving' is always a willing participant in the encounter. The females also have an unusually enlarged clitoris, which makes their ability to achieve sexual pleasure much easier.
