Why do animals mate for pleasure?
The primary function of sex is to reproduce, so it would make sense that nature would incentivise animals to mate by rewarding them with a pleasurable experience. We don't know how many animals experience sexual pleasure, but we have evidence for it in a number of species.
Really wild orgasms Not only do animals enjoy the deed, they also likely have orgasms, he 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.
To transfer their genes to the next generation successfully, animals need to choose a suitable mate. Failure to do so leads to low or no reproductive success — that is, poor fitness. But reproductive success can also hinge on the number of mates, and on social interactions that extend beyond mating.
All female mammals have a clitoris, the sole purpose of which is to react to sexual stimulation, and presumably this stimulation has evolved to be pleasurable for most species.
BONOBOS. It's probably safe to say that bonobos are the most sex-crazed mammals of all time. For bonobos, sex is not only highly pleasurable, it is also an important social tool: it reaffirms communal bonds, resolves conflict, relieves tension, and just generally keeps the peace.
Oral sex has been observed throughout the animal kingdom, from dolphins to primates.
This could be for evolutionary reasons, but the jury is out over whether it's likely just for enjoyment. The only other known animal to experience pleasure during sex is the female Japanese macaque, which has been observed orgasming - despite there being no direct reproductive benefits.
Unlike many other animals, dolphins do not mate purely for procreation. Rather, these highly social and intelligent animals have sex for pleasure as well. Further, this means they can have sex throughout the year, rather than being limited to a mating season.
Forced copulation occurs in many taxa, including mollusks, insects, fish, reptiles, mammals, and the 3% of bird species that have intromittant organs. Female unwillingness signals are often dramatic; male force can maim or kill females and reduce female lifespan; thus female unwillingness or direct physical resistance ...
