The scientific name for being aroused by excrement is coprophilia (or scatology); though play involving shit is more commonly known by the term scat. Both coprophilia and scatology are derived from an ancient Greek root word meaning faeces, excrement or dung, and these three words, as well as the word shit, relate to the solid excretory product evacuated from the bowels.
For most people, scat play is repulsive and off-limits. For some, it is still repulsive but holds some fascination and provides a means to explore degradation and humiliation or a means for a Master to assert more power and control over his slave, or develop a sense of worship and devotion. For a few, it is a real turn-on and is explored regularly, sometimes to extremes.
Scat play is a progressive, goal-orientated activity and it takes many training sessions for a Master to fully train his slave in this area. Some activities can be done with little or no preparation, though others require months of training to achieve any real level of success.
Shit play encompasses a range of sexual desire. Some scat players are only into the visual aspects, such as watching someone take a dump or looking at an unflushed toilet while aroused. Many are into smearing shit on their bodies. Some like to eat shit; a practise known as coprophagy. This eating can be during or outside of a sex session. Slaves trained in scat may have to lick their Master’s arse clean after he’s had a dump, or suck on a shitty cock, or lick his Master clean after a scat session. Some Masters, when preparing food for their slave property, will cook with shit (and piss). Others like to fuck shitty arseholes, sometimes which have been ‘repacked’ with someone else’s shit. Sometimes scat is part of a submissive desire to become a human toilet. Sometimes it's part of enema play. Still others are into ‘farming’ or gathering shit from public toilets. For most it is probably some combination of these activities. Some people act out these kinds of games as fantasy by substituting items like chocolate cake at the last moment. Occasionally, (and sometimes deliberately as part of the thrill and session) puke is involved. How this is dealt with depends on the Master. Some see puke as a minor irritation, to be ignored and cleaned up later, others aim to induce it and bring it in as part of the play, perhaps even as far as making a slave lick it up.
Mentally, scat play is multi-faceted as well. For some it is an extremely intimate exchange between those involved, almost a sacrament. Within slavery scat training is often to do with reinforcing the dominance of the Master. The slave is so submissive he even wants to eat his Master’s shit. A Master’s shit is also a focus of worship. Even the waste products from a Master are opportunities for worship and devotion, and are superior to the slave himself. For others it serves as the climax of a heavy BDSM or humiliation scene.
Interestingly, shit can be used to create human compost and is being done so by many successfully. It's worth any people who use shit play regularly and who have gardening interests to check out humanure.
Shit is not poisonous and playing with it generally is safe. Though having shit on unbroken skin can do little harm, there are some health risks attached to coprophagy, particularly involving the transmission of bacterial and yeast infections and viruses like hepatitis (although shit is not particularly a risk for HIV unless blood is present). Whether harm is passed on, of course, depends on the health of the feeder. If the Master and slave are faithful, then there is minimal risk, as long as the Master is not ill (when scat feeding should be temporarily suspended) and is clear of STDs.
About three quarters of an average turd consists of water, though this is highly variable. The water content of diarrhoea is, of course, much higher, and the amount of water in shit that has been kept inside (voluntarily or otherwise) is much lower. Water is absorbed out of faecal material as it passes through the intestine, so the longer a turd resides inside before emerging, the drier it will be.
Of the remaining portion of the turd, about a third is composed of dead bacteria. These micro-corpses come from the intestinal garden of microorganisms that assist us in the digestion of our food. Another third of the turd mass is made of stuff that we find indigestible, like cellulose, for instance. This indigestible material is called fibre, and is useful in getting the turd to move along through the intestine, perhaps because it provides traction. The remaining portion of the turd is a mixture of fats such as cholesterol, inorganic salts like phosphates, live bacteria, dead cells and mucus from the lining of the intestine, and protein.
The consistency of shit varies from person to person, and indeed, from day to day for the same person, depending on various factors. A useful reference guide is the Bristol Stool Guide. This is a medical aid designed to classify the form of human faeces into seven categories. The form of the stool depends on the time it spends in the colon.
Types 1 and 2 indicate constipation, with 3 and 4 being the "ideal stools" especially the latter, as they are the easiest to defecate, and 5–7 tending towards diarrhoea.
In humans, soft shit is really one long, mostly continuous sausage before it comes out. It gets its link look because we tend to pinch off lengths of it with the anal sphincter as the shit emerges. If a person pinches hard enough, the shit separates into several turd units. If the person doesn't pinch that hard, the turds may stay connected. If you push with your stomach you will be able to shit a long turd, unless there is a weak point in your shit. The reason shit separates when trying to produce a long turd is because of the weight and what the shit is made of. There are weak points in a longer turd and as the weight increases the longer the turd becomes, then there is a tendency, sometimes, the turd breaks at these weaker points. The longer a person waits the harder the shit can be and the less chance of having a weak point.
Floaters are turds that have an unusually high gas content. Sometimes the gases produced by bacteria in our gut don't have a chance to collect into a large fart bubble, but remain dispersed in the faeces. The shit then comes out foamy, and has a lower density than water.
Most people will experience a variety of different shades of shit during a lifetime. Shit is mostly shades of brown or yellow, but other colours can arise under certain circumstances. For example, someone with a bleeding ulcer might have tarry black shit from the presence of partially digested blood. Bleeding in the intestine, from an anal fissure or split, for example, can stain the shit red. Yellow shit, often leading to yellow diarrhoea is caused by a parasite. Intense red food colouring can produce bright red shit. Sometimes brightly coloured foods pass through the gut almost unchanged, and the turd may be speckled with it. Other colours can be seen due to medical treatments and medications. The red alert is black shit, resulting from internal bleeding.
The distinctive odour of shit comes from the products of bacterial action. Bacteria produce smelly, sulphur-rich organic compounds such as indole, skatole, and mercaptans, and the inorganic gas hydrogen sulphide. These are the same compounds that give farts their odour.
The skatole and mercaptan chemical components in shit are deliberately factored into the digestive process of most animal species. They don't emulate the smell of rot or putrefaction exactly, but they are often a fairly good proxy for it, especially once the shit has cooled. The chemical signals they send out are an assertive attempt to tell us to keep our distance. This is probably for the principle reason that shit is not, for most species, a substitute for nourishment. It's effectively spent material that contains, amongst other things, millions of dead or dying bacteria. It can also rarely contain harmful pathogens which can cause sickness if in contact with them.
However, very generally speaking, the intensity of the warning signals in the smell are not in proportion to the actual risks of making contact with shit. Just as the act of shitting itself is frequently and pleasurably auto-erotic for most people, the smell of shit can be incorporated, to varying degrees, into sexual consciousness to the extent that the smell becomes erotic in itself.
While there are things that can be done to moderate the smell of shit you can't get rid of it. Stink is part of the essence of shit. In general, what you must set out to do is to reprogram your brain so that the smell is no longer unpleasant.
Almost since birth, you've been brainwashed that the smell of shit is a 'bad smell' (and that shit was bad in general). The smell itself isn't really all that bad. All you have to do is gently undo that bad programming you've unconsciously received and replace it. It’s a matter of building familiarity and a Master training his slave in the correct way.
Generally, a good diet will produce good tasting shit. Eat lots but avoid high fat foods, such as most meats and junk foods, as excess bile is produced to digest them and this gives your shit a very bitter taste. Also avoid everything that gives you indigestion, beans that make you fart, extra spicy foods, and high roughage foods (at least in mass quantity) since this will make your shit loose and float – and sinkers are best. Eat lots of pasta, bread, grains, fruits, a bit of cheese, and very small portions of beef, chicken, seafood, and pork. A fibre supplement, taken regularly in very small doses might help.
Basically, the colon has two main functions: firstly, to carry shit along to the storage place (rectum) before discharge, and secondly to remove some of the water from faeces as a recovery mechanism. That is, as faeces moves from your small bowel to your large bowel /colon, it is very watery and the body reabsorbs some of that water from the shit to maintain water balance within your body. If your body is very hydrated (filled with more than enough water) your colon won't reabsorb much water from your shit. Similarly, if you're dehydrated, your colon will remove (reabsorb) more water from your colon in an act of conservation. Additionally, the more time shit spends in your colon, the more water that will be reabsorbed, and hence the firmer your shit will be.
There are many aspects of shit that are erotic for afficianados. Many of these are mental. For some the mere fact that it is so very taboo is enough to eroticise shit play. Add to that the fact that shit is highly symbolic, giving it a great mental kick. When you play with shit you are manipulating a huge variety of symbols and metaphors, many of them with powerful erotic content. For others, who find the exchange of power erotic, the complete submission given by accepting another's shit in or on yourself is the key erotic element. In addition, there is an element of challenge to shit play: it is hard sex. That challenge is, in itself, erotic. Also, shit is an offering from deep inside the body, making it very, very intimate. Finally, its association with the anal region, a highly erogenous zone, adds to its erotic power.
On the physical side, shit also has some very attractive elements. It's warm and squishy, like a fine mud on a hot summer day. The feel of shit on your skin can be very sensous. Even the smell, which we are programmed to dislike, avoid, and fear is actually an intense, rich, complex odor that can have many erotic elements if you just let yourself smell it.
Finally, perhaps the overriding element, the sum of all the others: shit is intense. Your whole body, your whole mind are wildly stimulated when you get into it.
