From everything I’ve seen on The Discovery Channel, intercourse in the animal kingdom lasts (sometimes significantly) less than 60 seconds. The male has an orgasm, but does the female ever? Do male’s orgasms produce the same euphoric effect as in humans?* Does the male do anything to further physically stimulate the female? I know that if I got my wife all worked up, screwed for 30 seconds, came and went to sleep, she’d file for divorce.
I hesitate to argue with the Master, but according to Bonk: The Curious Coupling of Science and Sex by Mary Roach female pigs are, in fact, capable of orgasm. It’s just that, like most female animals, they don’t show by their behavior that it’s happening.
Bonk has one hilarious chapter on government* pig inseminators that had been trained to, ahem, service the females in a way that ensured the production of more piglets. This included leaning on them and prodding under their bellies with their boots, to mimic the prodding of a boar, among other things. The only sign that the Big O had happened was that the semen feed would suddenly be slurped up like a beer-chugging freshman.
I really recommend this book.
*I forget which country, exactly. It was a Scandinavian country, though. The extra time and effort was only taken because it improved the offspring yield noticably.
My WAG is that orgasms are only nessacery in species intelligent enough to override their reproductive instinct (humans, dolphins, monkeys etc). If a species’ reproduction is driven by instinct, then sex doesn’t need to be gun.
“Bork Bork Bork” 
Per Wikipedia (Clitoris - Wikipedia, includes pictures), the clitoris is exclusive to female mammals.
I’ve heard that female humans sometimes have orgasms.
I had a Persian kitten that had orgasms…pretty intense ones, too.
There was never a MALE involved though. This cat had a thing for unwashed panties. She would drag them out of the laundry pile, wrap herself in them so that the crotch was in her nose ( she was a tiny animal ) and go town for abut 10 minutes, just purring and spasming.
It was very cute in a really pervy sort of way.
How do you think reproductive instincts work? The fact that sex is enjoyable is part of the instinct.
On TV it always is. Too much sex and violence.
Shouldn’t that be “Pork Boink Pork?”
That’s meant to be “fun” not “gun” :o
I don’t think that all animals get pleasure from sex (although I have to admit, I don’t know).
Then why do they do it?
Boredom. Remember that most animals cannot see a TV image.
Ah yes, that must be it.
Seriously, it seems to me that “it feels good” is the *only *reason for an animal who doesn’t understand reproduction to do such a silly thing. Think of those “animal drives” that humans have: when you’re hungry, your stomach hurts, and when you eat, it feels good. When you have to pee, it feels uncomfortable, and when you pee, it feels good. And don’t get me started on the pleasure of a really good dump!
It’s a pattern: need = discomfort, fulfillment of need = pleasure. I see no reason why an animal in estrus wouldn’t feel the same way - in pain, or at least uncomfortable, and sex makes it feel good. Certainly my cat in heat (damn her previous owner who swore she was fixed!) appeared very uncomfortable, and wagged her little ass in front of anything vaguely phallic, begging for some sort of action, the little tramp.
Sometimes, I’m dismayed by how many men appear to believe that sex is only enjoyable if you’re male. Or that women are somehow at a disadvantage because of our gender.
It took us a couple hundred years and the invention of the MRI to determine that the erectile tissue involved in the human clitoris is longer and more massive than the human penis. It was only a decade or so before that that we figured out that female orgasm served a purpose - pulling semen into the uterus.
Considering the risk of disease, injury, and death that comes with coitus, there had better be a damn strong overriding impetus that drives female animals, including women, to have sex. Pregnancy and offspring is far too separated from the act to be what drives sex. Humans are the only species to figure out that sex leads to offspring.
First, assume that sex, done right, feels good for everyone involved.
Second, understand that if sex is going to work, the good feelings will be as strong for females as they are for males. After all, the female assumes a hell of a lot more risk than the male.
As has been noted, female mammals have a clitoris. Which makes sense – it is simply the homologous organ of the penis in mammals, human or otherwise. It wasn’t a new feature of the human release that god tacked on at the last moment, despite the invocation of his name when in use. There’s no doubt that many female mammals will have an orgasm if handled properly. If one has the right combination of bravery, curiousness, and perversion you can find video evidence of this on the intertubes. Or so I hear.
Of course, whether this happens with any regularity in nature is another question. Like the OP, whenever I see a nature documentary it would seem that most male mammals have the staying power and thoughtfulness of a 13 year old boy.
IIRC, most other mammals have their clitorises situated so that they’re stimulated directly by the male’s penis. Human sex is pretty exceptional in a lot of regards, and this is one of them.
So a group of men who all went to the same church got together to talk. The preacher of the church was among them. After a while, sure enough, the topic turned to sex. The preacher, feeling obliged to keep the conversation from going too far astray, said “I don’t know why everyone’s always talking so much about sex. After all, it doesn’t feel any better than taking a good dump.”
There was a moment of silence, when one of the other men said "Preacher, either YOU don’t know how to FUCK,
or I don’t know how to SHIT.
Well, they say they do, but I think they’re just faking it.
