I cannot name any animal that moans during sex. Some may grunt or salivate or make sounds of exertion but loud pleasured moans are not heard in the animal kingdom. I presume it is a survival instinct so as to not give away the location at a time when they could be vulnerable to attack.
Why are humans not evolved similarly. The survival instinct and prey vulnerability must have been the same for millions of years of our evolution. How come human sex is so noisy.
Culturally reinforced behavior? In that our self-awareness tells us grunting and chuffing is “rude” while making passionate sounds is not?
Humans also say “Mmm” when eating something yummy.
We make noises for a variety of reasons – with sex, it seems like most of it is for communication to partners.
The breathing, the panting, the moaning, the screaming :Fake, fake, fake, fake
Not really fake, I always thought so in the past. I was probably close to 50 years old before I learned how to really let go during sex and I make a lot of noise none of which is fake. It is really far more intense and satisfying.
I’ve heard tell on one documentary that some in the scientific community suspect that “face to face” sex is one of the factors that led to the spoken word. Basically through the exchange of facial expressions and sounds made.
I don’t think this is correct. It’s not uncommon for female primates to vocalize; see e.g. Women in Bed: What's All the Noise About? (Part II) | Psychology Today
Red Foxes are fairly well known for screaming during sex.
Female cats cry out. The male has a barbed penis. Unverified, saw something that said the pain causes the female to ovulate.
Don’t domesticated cats famously make a horrible racket when mating?
Ninja’d
Yet quite a few animals are stuck together for quite some time after the deed is done during sex, they’re pretty vulnerable at that point. I don’t feel like googling to find out the details.
I wonder though, is that part of the reason that for humans at least sex is considered a private activity (in general, there’s always one…well two…), in pre-history you needed to be somewhere safe and secure while doing it as people tend to be somewhat distracted and not paying full attention to their surroundings.
Is that before or during sex? I thought the mating call was the fox looking for a partner.
This thread is an education.
Male rabbits also squeal at orgasm ( and promptly fall over afterwards ).
Lions also get noisy.
Fairy (little) penguins apparently create a lot of racket during mating, in Australia if you get a mating pair to have a go at it in your house (or the crawl space or whatever they can access) it is considered good luck.
Because barking out orders only turns on some people and “You’re getting warmer” seems inappropriate.
It’s a quote from Seinfeld, when Elaine told Jerry she faked all her orgasms with him 
When I was on a trip to the Galapagos Islands, I had the opportunity to watch some tortoises mating - the males make very unusual moaning noises throughout the process (which is pretty slow, they are tortoises).
Peacocks also make quite a ruckus while mating. It’s a horrible screeching noise that sounds like an infant crying.
Humans in the culture that you know about are having sex for recreational purposes. If you were to observe sex in a culture where men simply took the women in order to spread their genetic material, there might be a short supply of what you call moaning.
Consideration of this makes me wonder: at what point did sex come to be regarded as a mutually pleasurable experience between humans? I don’t think most animals (other primates, probably, but few others) have a lot of fun when they’re doin’ it. Why do we? What is the evolutionary advantage? Ostensibly humanity could get the same reproductive result from clubbing and raping.
I same to remember reading a book at some point in college that talked about this and at least this humans go the thought it was that making it a pleeasurrable experience would be a good thing to keep the male and female together. Maybe help raising the kid as a family unit since children take so long to meet your into adulthood or at least reproductive age.
I wanna day the book was The Water Ape. The book also talked about the presents of breast that hang outside the body in a female was a bonus for the male to look at so he was likely to mate face to face and that would imprint the desire to care for the female whilst she is pregnant for 3/4 a year.
