GAY MEN'S HEALTH - Part 2-(Mouth,Throat & Digestive system)
Body Stuff - The mouth and throat
The mouth is the beginning of your digestive system. The throat is situated behind the mouth and joins the pharynx to the oesophagus, the tube which takes food to the stomach. The mouth is covered with soft mucous membrane and smooth muscle generally resilient to bacteria and other infections. The tongue is a multi-skilled muscle which helps us to speak, taste and position food for chewing before moving it to the back of the throat for swallowing. But like, every muscle, it can grow tired with over-use and can be strained, which is why prolonged cocksucking can be exhausting and no longer a pleasure. Our tongue is covered in taste buds which can determine four primary taste sensations: sour, salt, bitter and sweet. All other flavours such as chocolate, pepper and coffee are combinations of these four, accompanied by the sense of smell. The tongue has three taste zones: salty and sweet (to the front and tip of the tongue), sour (to the sides) and bitter (to the back and centre of the tongue).
Saliva
The mouth contains three pairs of saliva glands: beneath the tongue, on either side and to the top of the mouth. Chemically, saliva is 99% water and 1% a digestive enzyme and (in addition to chewing) helps to break down and lubricate food before swallowing. Saliva also destroys bacteria to protect the mucous membrane from infection and the teeth from decay. Saliva is produced continuously to lubricate the mouth and to keep the tongue and lips moist. During stress, the production of saliva decreases to conserve water. A dry mouth contributes to the sensation of thirst and drinking will not only moisten the mouth but also help restore the body's water and chemical balance(homeostasis).
Gagging, coughing and choking
Sensitive muscles to back of the mouth detect sharp, rough or large objects and will trigger the gagging reflex to prevent them from passing into the throat. The coughing reflex also aims to remove foreign or unwanted objects from the throat and oesophagus such as large or sharp pieces of food, dust and pollen. Consequently, deep throat sucking comes with practice as you re-programme your brain not to reflex.It's also worth remembering that when we swallow, a small flap (the epiglottis) in the oesophagus usually closes the opening to the larynx which leads to the lungs. When food or drink 'goes down the wrong way', the flap doesn't close in time and we start to cough to get it out of the airway and back on track down the oesophagus to the stomach. Choking, on the other hand is when we don't get enough air and our body reflexes, demanding more.
Body Stuff - The Digestive System - Part 1
Your arse is just the beginning - or rather the end - of your digestive system, which extracts nutrients and goodness from the food we eat. What's left is waste which we get rid of as shit. Many people believe that the digestive system is just a small tube linked to the stomach where shit sits waits for the rectal express to the toilet. In fact, from mouth to arsehole, it's a nine metre (30 foot) rubber-like tube, lined with muscles which massage the food and waste along, regulated by a series of locks and chambers.
The stomach
After swallowing, food travels down the oesophagus to the stomach - a 'J' shaped organ about 30cm long - where it stays for up to 6 hours. Here, acids and enzymes digest food until it becomes a semi-liquid soup which you have probably seen as vomit (with diced carrots). The speed at which food moves on from the stomach depends on what you've eaten and what's going on further down the line. Nerves which connect the arse to the stomach transmit messages to control the flow of food and waste. For example, you may experience discomfort or pains in your stomach if you are constipated or being fucked or fisted. Conversely, when you eat, you often want to go for a shit.
The small intestine
In a semi-liquid form, food is passed along the duodenum to the next stage of digestion: the small intestine, a long rubbery tube, 2.5cm (1") across and some 6.5m (21') long. It's here that the nutrients and goodness in food are extracted.
The large intestine
What remains resembles a rich vegetable soup, which passes into the large intestine. This is rather like an inverted 'U' shaped pipe which joins the small intestine at the bottom right-hand corner, near your appendix. This is made up of the ascending, transverse, descending, and sigmoid colons. It is here that the waste becomes more solid as the water and salt is absorbed back into the body. The sigmoid colon is best described as the final packaging and holding bay for shit. The rectum is the dispatch area and the anal canal to your arsehole is the main exit. By the time shit leaves the sigmoid colon and reaches the rectum, it is normally produced in discrete turds of a good consistency and reasonable size.
The rectum, anal canal and arsehole
Around the connecting tube between your sigmoid colon and rectum is a ring of muscle that angles the tube in such a way as to close it off. This sphincter muscle regulates the shit leaving the sigmoid colon; without it, your rectum would fill up continuously and you would be shitting all the time.
Your rectum is a stretchy four to five inch (10-13cm) muscular tube that can stretch to the size of a clenched fist (when full of shit) or a hand. Below your rectum is the anal canal, 1-2 inches (2-5cm) long which ends in your arse hole. The surface of the rectum and the anal canal is usually covered with a thin layer of mucus or natural lubricant designed to help with shitting and which also helps offer protection from infections. If you rub the surface, you quickly exhaust the supply of mucus which is why you need additional lubricant when putting anything up the arse.
At the bottom of the anal canal is another sphincter muscle made up of two smaller interconnected rings of muscle. One of them is not under your direct control but responds to internal body messages when the rectum is full or when you cough - the muscle tightens. When the muscle doesn't work properly you leak. You have more control over the other muscle which you can relax or tighten at will. Try it now - you see control is everything!
Shitting
The weight of shit stretching the sides of the sigmoid colon signals the top sphincter muscle to relax briefly allowing a measured amount into the rectum. This is also called a movement. If you're ready to go and sitting on a toilet, the bottom sphincter muscle relaxes and lets the shit down the anal canal and out through your arsehole.your arsehole.
hile big long cocks can have your arse poked skywards in seconds, they can knock into the rectum wall and sphincter muscles causing discomfort and pain. So the moral of this tale is quite simple: don't ignore smaller cocks and beware of bigger ones in the hands of dickheads who think they know what they're doing. Later on in the book describes how you can reduce the risk of pain and potential damage - and how to order him a taxi!
Body Stuff - The Digestive System - Part 2
The rectum only senses enlargement and stretch, while the anal canal can sense temperature, touch and pain. This makes the anal canal more fun to play with than the rectum which will only notice if you stretch its walls. Above the rectum there are no receptors to sense pain or injury so penetration beyond this point is more risky. Located to the front of the rectum (tummy side) is your prostate gland, doughnut-shaped and about the size of a chestnut. Stimulating or rubbing during sex can be a big turn on which is why getting fucked in the right position can be so pleasurable. However, the prostate is very sensitive to pressure and harpoon guns!
Complications
There are many factors involved in shitting properly and some of these can go wrong. If your sphincter muscles don't seal properly then you may leak or shit yourself. Ulcers or a split in the anal canal may mean you get pain and a tighter sphincter muscle. If you regularly use laxatives, you may damage the nerve supply to this area and then either get diarrhoea or constipation. If you experience anything out of the ordinary or have any concerns, go to a doctor. Prevention or early treatment is preferable to suffering, or getting serious complications needing surgery.
Diarrhoea
Diarrhoea is usually caused by an irritation of the intestine lining or infection in your small or large intestine. Quite simply, your body wants to get rid of the problem and, if it can't vomit it out, it will shit it out as quickly as possible. The muscles which massage food through the digestive system go into over-drive (which is what can cause stomach aches, pain and cramps). To help flush out the problem, the locks and valves regulating the flow open up; however, this also means that there isn't enough time to extract the water from the waste and it's at times like this that your bowels just open to release that all-too-familiar brown sludge. Oddly enough, we sometimes underestimate our body's ability to deal with situations like this. Generally, speaking, it is best to let nature take its course - not forgetting to drink lots of fluids(containing salt and sugar) to help wash out your digestive system and prevent dehydration. However, if symptoms persist, get it checked out.
Constipation
Constipation may be caused by spasms in the large intestine, insufficient bulk or roughage in your diet, lack of exercise or stress. Shit passing through the colon, which extracts just enough water to turn the sludge into solid turds, can get stuck there and continue to dry out until they become hard and knotted. Shitting is then painful as the hardened turds rub abrasively against the walls of your colon, rectum and anal canal.
Haemorrhoids Piles
Haemorrhoids are veins near the surface of the bottom part of your anal canal that have become inflamed, forming pockets or mini-bags of blood. Initially, they'll stay inside the anal canal but can, over time, get larger and are pulled towards your arsehole by the downward motion of shitting. If constipated, straining makes them much worse. Sometimes they split open and can bleed, often quite profusely. Sometimes the blood work itself out of the bags back into the body and the haemorrhoids heal themselves. Suppositories (bullet shaped tablets which you slide up the anal canal) or creams (which you rub onto the entrance of your arsehole) will often alleviate the discomfort and pain of shitting. However, if symptoms persist, it's important that you get yourself checked out by a sexual health clinic or by your doctor.your arsehole
Body Stuff - Diet
Lowering stress levels, taking regular exercise and eating a balanced diet all play important roles in ensuring that your digestive system works well and is problem-free. Dietary advice to prevent constipation is based on the effects of certain foods being able to resist digestion. Such foods increase the weight (and volume) of shit, and are also able to bind water more effectively, forming a turd that is softer and easier to shit from the body. Fruit and vegetables, both cooked and raw, whole-grain cereal products such as brown rice, wholemeal bread, flour products and wholewheat breakfast cereals are excellent turd-bulking agents and the maxim is the more the merrier. Pulses, such as lentils and beans, are also known to be effective, although the novice may become rather farty and will need to adjust intakes accordingly. The addition of bran to the diet (along with sufficient fluid intake) can provide some relief from constipation, although this should not be a substitution for a healthy diet. Foodstuffs which are more likely to lead to constipation include dairy products, fatty foods and foods which have little or no fibre. If you experience pain, discomfort, if you're not shitting softish turds regularly or if you have any concerns - visit your doctor. Some GUM/STI clinics offer advice and information on diet and healthier living.
