Most primates mate facing the same direction. "Bonobos [mate face-to-face] routinely—zoo gorillas and zoo chimps too," said Craig Stanford, an expert in great ape behaviors with the Jane Goodall Research Center at the University of Southern California (USC).
Bonobos are the only non-human animal to have been observed engaging in tongue kissing. Bonobos and humans are the only primates to typically engage in face-to-face genital sex, although a pair of western gorillas has also been photographed in this position.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
What is face to face mating? Hihi copulate in two different positions: face to face and, more conventionally, with the male on the female's back. Face-to-face copulation is unique among birds and appears to be a form of forced copulation. The presence of enlarged cloacas in both sexes could aid the transfer of sperm.
The two species are evolutionarily too distant and their DNA is too dissimilar for a gorilla and a chimpanzee to produce offspring.
Just like humans, monkeys have many different relationships when it comes to mating and reproduction practices. But how do monkeys mate? They can mate monogamously, have a harem, or practice polyandry.

Sexual intercourse both culminates and terminates in orgasm, a process in which the male expels semen—containing sperm cells, which may unite with and fertilize the female's egg, and a seminal plasma that contains cell nutrients, water, salts, and metabolites—into the female's vaginal canal.
Due to the much larger evolutionary distance between humans and monkeys versus humans and chimpanzees, it is considered unlikely that true human-monkey hybrids could be brought to term. However, it is feasible that human-compatible organs for transplantation could be grown in these chimeras.
Oral sex has been observed throughout the animal kingdom, from dolphins to primates.
Many animals actually do engage in kissing-like behaviours to show affection. These behaviours are so diverse, from dogs sniffing and licking potential mates, to elephants putting their trunks in each other's mouths. However, one animal kisses just like we do: the bonobo ape.
Our oldest evidence of penetrative intercourse is about 385 million years old and comes in the form of fossilized remains of the way too aptly named Microbrachius dicki.
Because the female orgasm is just as important as the male experience, and it should never be ignored. Women should come first; it's totally achievable.
A large-scale study found that human copulation lasts five minutes on average, although it may rarely last as long as 45 minutes. That's much shorter than the 12-hour mating roundsseen in marsupial mice, or the 15-minute couplings for orangutans, but longer than the chimpanzees' eight-second trysts.
In typical bird copulation, males and females momentarily press together their cloacas – genital openings – in what biologists call a cloacal kiss.
If you offer your bird full body strokes, you are actually stimulating the production of sexual hormones. Petting down the back or under the wings can lead to a sexually frustrated bird, or a bird who perceives you as a mate rather than a companion.
Regardless, the scream is really loud. In fact, researchers from the University of Massachusetts Amherst and the Instituto Nacional de Pesquisas da Amazônia report that the mating cry of the bellbird is the loudest bird call ever measured, topping out at around 125 decibels.
“Small-bodied and vulnerable adolescent female Japanese macaques may prefer to engage in relatively safer sexual interactions with female monkey sexual partners in lieu of riskier sexual interactions with more aggressive male mates,” Gunst-Leca says, explaining that sometimes humping other animals is safer than hooking ...
In fact, such human-animal hybrids are often referred to as “chimeras”.
Not only do animals enjoy the deed, they also likely have orgasms, Bekoff said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.
a) Dogs and cats are not like people when it comes to sex. They don't cycle the same way and there's no evidence, behaviorally or otherwise, that sexual activity brings them any specific pleasure akin to orgasm, for example.
