1. Brown antechinus. For two weeks every mating season, a male will mate as much as physically possible, sometimes having sex for up to 14 hours at a time, flitting from one female to the next.
The animal that has the most pleasure during mating or sexual intercourse is the Bonobo. It would be safe to say that Bonobos are the most sex-crazed animals that enjoy having sex to their fullest. Also, their sexual behavior and activities are insanely identical to humans.
Bonobos are highly promiscuous, engaging in sexual interactions more frequently than any other primate, and in just about every combination from heterosexual to homosexual unions.
A large-scale study found that human copulation lasts five minutes on average, although it may rarely last as long as 45 minutes.
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.
In fact, such human-animal hybrids are often referred to as “chimeras”. While this scientific advance offers the prospect of growing human organs inside animals for use in transplants, it can also leave some people with a queasy feeling.
In addition to standard penetrative encounters, they frequently engage in manual genital massage and oral sex. These positionally creative apes are also the only animal (other than us) to practice tongue-on-tongue kissing or face-to-face penetrative sex.
Animals that mate for life: beavers
Not much is known about how beavers find their mates, but once they do, they stick with that partner for life. A genetic study by Charles University in Prague even found that beavers stay faithful to their mates. Granted, this only applies to European beavers.
These evolutionary measures might not necessarily be humans' idea of romance, but there may also be scientific evidence that animals that mate for life have feelings for each other. Prairie voles are more receptive to dopamine — the “desire hormone” — after mating.
Gibbons. gibbons (family Hylobatidae) Edmund Appel/Photo Researchers, Inc. These agile tree-dwelling apes act like humans in that they occasionally cheat on their mates, sometimes break up, and later get back together again.

The sperm are transferred while the person with a uterus is lying on their back.
Male kalutas, small mouselike marsupials found in the arid regions of Northwestern Australia, are semelparous, meaning that shortly after they mate, they drop dead. This extreme reproductive strategy is rare among vertebrates —only a few dozen are known to reproduce in this fashion, and most of them are fish.
As some of the first bands of modern humans moved out of Africa, they met and mated with Neandertals about 100,000 years ago—perhaps in the fertile Nile Valley, along the coastal hills of the Middle East, or in the once-verdant Arabian Peninsula.
Thus, privacy, or perhaps more accurately, seclusion, allowed the male to maintain control over a sexual partner—while also allowing for continued cooperation within a group.
It happens in both animals and plants. Such encounters can affect the conservation and evolution of a species. When two different species successfully mate, the resulting offspring is called a hybrid. Hybrids are often, but not always, sterile (think of mules).

Animals do not have genders. And although this statement is universally accepted by those who study and theorize about gender, there is a lot of confusion about it among those who do not. The confusion stems from the fact that males and females of many species systematically behave in different ways.
Wild house mice rely on specially evolved proteins in their urine to sniff out and avoid mating with their close relatives. In many social species the trick is that one sex, usually the female, leaves the group at adolescence. That way they can't mate with their own family.
The first successful human-animal chimeras were reported in 2003. Chinese researchers at the Shanghai Second Medical University successfully fused human cells with rabbit eggs. They were allowed to develop the eggs for several days in a petri dish before the embryos were harvested for their stem cells.
But creating hybrids of animals that are very genetically distinct from each other—such as a dog and a cat—is scientifically impossible, as is one species giving birth to an entirely different one. That has not stopped people from hoping.
Aardvarks, aye-ayes, and humans are among the species with no close living relatives. There are 350,000 species of beetles—that's an awful lot of relatives.
Oral sex has been observed throughout the animal kingdom, from dolphins to primates. Bonobos have been observed to transition from a simple demonstration of affection to non-penetrative genital stimulation. Animals perform oral sex by licking, sucking or nuzzling the genitals of their partner.
