Thread: Consciousness, Orgasm, and Evolution

Lol I was going to make a semi-literate post for this one too...

There is masturbation in animals, homosexuality ..
Checked out Wikipedia - seems there is no overall consensus - but "animals mate only for reproduction" is doubted with reason.
I´m going with Snopes - that animals do have orgasms and feel pleasure can´t be refuted with the usual arguments.
And the Danes - it is highly likely they do.

Bit overkill - don´t ask why I got myself into this thread and post something - purely arbitrary ..
But for who is interested (a lot):

Sex for pleasure

It is a common myth that animals do not (as a rule) have sex for pleasure, or alternatively that humans, pigs (and perhaps dolphins and one or two species of primate) are the only species that do.

This is sometimes formulated "animals mate only for reproduction".

Science cannot conclusively say at present what animals do or do not find "pleasurable," a question considered in more depth under Emotion in animals.
The urban myth (busting) website Snopes .com* considers this particular view in depth.

Its conclusions are broadly that the statement is true, but only using a very specific definition of "sex for pleasure," in which sexual acts tied to a reproductive cycle or for which an alternative explanation can be asserted, are ignored, as is all sexual activity that does not involve penetration.
Animals put themselves at risk to engage in sex, and as a result, most species have evolved sexual signals (usually scent and behaviour) to indicate the presence of receptive periods.
During these, sex is sought, and outside these it is usually not sought.
Snopes comments that this is not in fact a reflection of whether sex is pleasurable or not, but rather a reflection of whether individuals have sex at arbitrary times.

They conclude:

Of course, we have to make many seemingly artificial distinctions to arrive at our conclusion (that they do it reproduction only).

Animals other than humans have no awareness that their sexual activities are connected with reproduction: They engage in sex because they're biologically driven to do so, and if the fulfilment of their urges produces a physical sensation we might appropriately call 'pleasure, it isn't the least bit affected by the possibility (or impossibility) of producing offspring.

We are also discounting cases in which animals do engage in sex even though reproduction is an impossibility because we claim there are other 'purposes' (of which the animals themselves are unaware) at play.

For example, the females of some species of birds will invite males to mate with them even after they have laid their eggs, but we ascribe a purpose to this behaviour: this is a biological "trick" to fool males into caring for hatchlings they didn't father.

We also employ subjective terms such as 'willingly' and 'regularly' in claiming that bonobos and dolphins are the only other animals who "willingly (and regularly) engage in sex with each other" ... and even then it may be the case that these species have some other 'purpose' for doing so that we haven't yet discovered...


A 2006 Danish Animal Ethics Council report which examined current knowledge of animal sexuality in the context of legal queries concerning sexual acts by humans, has the following comments, primarily related to domestically common animals:

Even though the evolution-related purpose of mating can be said to be reproduction, it is not actually the creating of offspring which originally causes them to mate.
It is probable that they mate because they are motivated for the actual copulation, and because this is connected with a positive experience. It is therefore reasonable to assume that there is some form of pleasure or satisfaction connected with the act.

This assumption is confirmed by the behaviour of males, who in the case of many species are prepared to work to get access to female animals, especially if the female animal is in oestrus, and males who for breeding purposes are used to having sperm collected become very eager, when the equipment they associate with the collection is taken out.


There is nothing in female mammals' anatomy or physiology that contradicts that stimulation of the sexual organs and mating is able to be a positive experience. For instance, the clitoris acts in the same way as with women, and scientific studies have shown that the success of reproduction is improved by stimulation of clitoris on (among other species) cows and mares in connection with insemination, because it improves the transportation of the sperm due to contractions of the inner genitalia. This probably also concerns female animals of other animal species, and contractions in the inner genitals are seen e.g. also during orgasm for women. It is therefore reasonable to assume that sexual intercourse may be linked with a positive experience for female animals.

Female crocodiles do have a clitoris as well - don´t know if they masturbate (nice mental picture I got myself now..)

I have sex with animals, because I'm a Dane.
