Candles
Candles Playing with hot wax can be exciting, but painful if you don't do it right. Start off by using plain white paraffin candles because the colouring and dyes in some candles can raise the melting point of the candle-wax to a point where it becomes uncomfortably hot. Avoid beeswax candles, which also have a high melting point and can burn skin. Generally soft candles have a lower melting point and are safer.  Fire and Ice  is the use of hot candle-wax alternated with ice cubes. Candles
Cane
CaningTraditionally associated most with the English schoolroom, the swishy cane is the stuff of school-day fantasies the world over when naughty boys or girls are made to 'bend over' for 'six of the best'. Canes come in a variety of lengths and thicknesses and are traditionally made of rattan, although more recently man-made materials like fibreglass have become available. Depending upon how the cane is applied it can simply sting or it can raise severe welts. Usually applied to the bottom but occassionally ( in school-room role-play) to the palms of the hands. Generally bottoms and submissives are sharply divided over canes, either loving or hating them. This isn't surprising because canes can hurt a lot. The pain tends to come in two waves, first when the cane strikes and then again slightly later as the indented tissue decompresses, which is why an experienced and sadistic caner will take his time and allow a delay between strokes so that the 'lucky' recipient receives the full benefit of each stroke. If you're doing the caning, practice first. It may sound silly, but have a few swishes at a cushion to get the feel of using the cane. Take a couple of strokes yourself so you know what it feels like. When caning, always strike well-padded fatty tissue, not where bones are close to the surface. Never hit the spine or tail-bone, because you can do serious damage there. The same general precautions apply to 'spanking' with other hard implements.
Cat 'o' nine tails Catharsis
Cat 'o' Nine TailsOriginally used by the British Navy to flog uppity sailors, this was a leather whip with nine thongs which were sometimes weighted with lead to produce a devastating punishment that could strip the skin off right down to the bone. The torn backs of the whipped sailors who survived the punishment (and some didn't) were then rubbed with salt or bathed with sea-water, partially to increase the pain but also to disinfect the wounds. Not nice at all and one reason why they had to use press-gangs to kidnap young men to serve in the navy. Nowadays the cat 'o' nine tails is often a term used to refer to any multi-thonged whip.  CatharsisThe purging of emotions or tension. People may bring to BDSM sessions issues of self-esteem and past psychological trauma. The intense emotional charge generated by some BDSM encounters can be the catalyst which brings these issues to the surface. This can be either good or bad, depending on how its dealt with. Certainly at a simple level it can sometimes be therapeutic. I've often heard 'bottoms' say that when they get really wound-up and cranky,  theres nothing works like a good hard spanking to purge the stress and re-focuss the mind. While I can't  see your doctor prescribing one for you, it may well be a whole lot more fun than prozac.
Clamps and clamping
Clamps and ClampingMechanical devices that make you go 'Ouch', clamps come in various shapes and sizes but they are all designed to cause pain through pinching or squeezing. They can include nipple clamps, crocodile clips or even the humble clothes-pin and are applied to erogenous areas such as nipples, cocks, balls or the vulva. Weights are sometimes added to increase the intensity of the pain. The pain caused by, for example, a stroke with the cane is transitory but something like a clamp applied to sensitive flesh causes consistent discomfort so keep checking how the person wearing it is feeling and don't forget its there. They certainly won't ! Clamps hurt most when they're removed and the longer they've been on the more they hurt. Its also possible, if you're looking for a seriously intense jolt of pain,  to attach several smooth clamps together to a chain or cord (the technique is sometimes called a 'zipper') so that they all can be pulled off simultaneously. Ouch !!
Cock and Ball Torture (CBT)
CBT - Cock + Ball TortureOften applied (consensually) by a Dominatrix or sometimes even self-inflicted, the variety of torture that can be inflicted upon these ultra-sensitive areas boggles the imagination. Commonly used are clamps, clips, tight bindings of various sorts, whips, crops, electrodes, and hard-core addicts have even been known to hammer nails through their unfortunate appendages. The golden rule, as with so many things in BDSM, is to take it easy. Go slowly until you know how much you can take. If the pain from a particular activity starts to spread into other areas of the body, or if the pain lasts for a long time after the stimulation ends, you have probably gone beyond your limits. If the pain persists for any length of time after the activity has stopped you may need to see a doctor. Definitely avoid any harsh wrenches or twisting of the genitals because there are ligaments and blood vessels that can be damaged.   Above all remember that if you're entrusting the family jewels to the tender mercies of someone else, you need to make damn sure they know what they're doing or you could end up with some very nasty injuries. See also pussy torture for some tips on tormenting her pretty pink parts.
Cock-Rings
Cock RingsCockrings are, as the name suggests, rings that go around your cock. Usually they go around the base of it, behind the balls. The penis becomes erect when the blood vessels at its base constrict (because of arousal), trapping blood in the cock and causing it to swell and prolonging erection. They're often used as an aid to impotence, or simply to prolong and increase the pleasure of an erection. Some are made of leather, with adjustable snaps, so you can tighten or loosen them to fit . Some are made of rubber. Some are even made of metal, but metal ones can be risky because a too-small one can become immoveable as your limp cock becomes erect and too 'big' for the cock-ring. Some cock rings have multiple rings, for behind the balls, around the balls themselves, and around the base of the shaft. See also The Gates of Hell
Collar (Collaring)
CollarA collar in physical appearance is usually like a dog-collar, made of leather or a chain, and worn around the neck (although some favour a symbolic thin gold chain for everyday wear). The conventional collar may be used as a prop in BDSM 'play'  to denote a negotiated submission but it can also have a much deeper and more permanent meaning than that.  In some D/s relationships  a collar is the outward symbol of a deep commitment, signifying that the submissive is owned by a particular dominant. A 'collaring' is the ceremony in which a submissive formally accepts the dominant's "collar" and becomes "officially" owned. It is the BDSM equivalent of a wedding, and may be witnessed by friends and others in the lifestyle. In the same way as a wedding ring is the visible sign of one kind of highly committed and exclusive  relationship, so a collar can signify at least an equal degree of commitment between some dominants and their submissives. 'Collaring' someone can therefore be a serious step in a relationship and shouldn't be taken lightly. It involves the dominant in accepting responsibility for the 'owned' person, and the submissive in giving absolute submission and loyalty to the dominant. Any 'dominant' who 'collars' someone he barely knows because he thinks its 'cool' to have a slave hasn't a clue about the significance of what he's doing and should be avoided like the plague. Any submissive who accepts a collar lightly and then betrays or knowingly dishonours her master by her behaviour really isn't worth much as a submissive. It all depends if you believe in it. If you do, then collaring is very important. If you don't, then its just one of the many props of an exciting 'dressing up to play BDSM' game. 
Contract  ( Slave Contract )
Slave ContractAn agreement which formally sets out the roles, responsibilities and limits of a Domination/submission relationship, sometimes called a slave or ownership contract. There are mixed views on the value of these contracts. Those who like them suggest that they are useful because they force parties to think carefully about what they are prepared to put into a relationship and what they expect out of it. For some this process provides a welcome sense of clarity as well as security. It can aso create a feeling of commitment and help to avoid potential points of conflict later on. Those who dislike the idea of such contracts argue that they are ultimately worthless. The basic concept fails because, unlike the legal contracts upon which they are modelled, slave contracts are totally unenforceable. Ultimately, a master will keep his slave, or a slave will agree to be owned, for as long as either chooses and there is no way of preventing either simply walking away from any contract whenever they feel like it. Some would argue that the only thing strong enough to really bind a Master and slave together is love because it is the only thing which has the power to keep you tied to another person when convenience or common-sense tells you to leave. If a contract feels right for you then it probably is, but don't rely on it too much. It is certainly no substitute for the communication between dominant and submissive that is essential both before and during any committed D/s relationship. 
Counting strokes
Counting Strokes - Spanking'One Sir' ..'Two Sir' .. 'Thank You Sir' .. 'May I have another Sir'. A ritualized counting of the strokes of a caning, with the recipient sometimes being required to thank the dominant after each stroke. If the submissive miscounts a stroke or remains silent, then the stroke may be repeated. As a custom, it has its roots back in the formalised canings once carried out in English public schools and was intended to assert the dominance of the caner and to humiliate the person on the receiving end by making them complicit in their own punishment. Of course if you're a committed masochist then you're not going to pass up the chance to get the count wrong, are you ?
Cross-dressing
Cross-DressingDressing in the clothes of the opposite gender is a particular fetish. For most of the latter-half of the 20th century its been perfectly acceptable for women to dress in masculine clothes, but its always been considered oddly shameful for men to dress in womens clothes . There have however been puzzling exceptions. A big butch chap wearing a frilly pink skirt would have always caused eye-brows to be raised in polite circles, but the same fellow wearing a kilt and muttering in an incomprehensible Scottish accent would have been considered quite manly. Go figure ! Great cross-dressers of recent history include Marlene Dietrich the film star and, allegedly, Edgar J Hoover, head of the FBI, scourge of so-called  'communists' and would-be tough-guy. See also Transvestite and Transsexual
Cruxifiction Cutting
CruxifictionAs the term is normally used in BDSM, it refers to a kind of bondage where the submissive is tied to a cross. Care needs to be taken to make sure that the weight is supported evenly and that the submissive can breathe properly. More rarely, hard-core devotees go further and actually have themselves nailed to a cross just like the romans used to do, but you really don't need me to tell you that this is risky and not good for your health.  CuttingGenerally means slicing the skin with a sharp implement (knife or scalpel) so that blood is shed (see bloodsports). Best avoided, but if you're turned on by the risky nature of this type of play, the sting of the blade as it slices flesh, the spilling of blood, then you also need to have a good  understanding of human anatomy so you don't slice into an artery and kill yourself by accident and also of sterilisation so that you don't create a nasty infection.
Cuffs or cuffing
Cuffs, Cuffing, HandcuffsCuffs can be made out of leather, cloth or metal and are designed to restrain the wrists or ankles. Bare metal  handcuffs can easily be shut too tight and impair circulation as well as causing chafing.The better leather or synthetic cuffs generally have some form of fur or sheepskin padding inside. The quality of the cuffs available commercially is hugely variable, and so its worth buying from someone who understands the uses to which  cuffs might be put and is able to offer suitable products. For example, using cuffs as a playful symbolic restraint is quite different from using cuffs to bear a persons suspended weight. Make sure the leather or fabric is cleanly cut with no sharp edges, and preferably lined to reduce the risk of chafing, with strong, secure fastenings of smooth metal (no sharp edges) or velcro. 
Cybersex ( online sex, virtual sex, virtual sceneing )
CybersexA wild new sexual frontier or the last resort of the unlovely and unloved ? Cybersex refers to 'sexual' encounters that take place with other people in 'cyberspace'  via a computer. Some call it 'sex between minds'. Some call it a bunch of sad old wankers.  Internet Relay Chat (IRC) has traditionally been the medium of choice, but more recently there has been an explosion of instant messaging (IM) services and even webcams which add a new dimension to this growth-area of social activity.  In simple terms, IRC is a means of conversing in 'real-time'  via your computer keyboard and screen with someone else on the internet. It has the immediacy of any 'real-life' conversation but, if desired, an even greater anonymity than email. You can either talk to people direct, person-to person in a private conversation not visible to others, or you can join a chat-room (or channel) to talk. A chat room is like a public room with a lot of people in and you can see all of their conversations on your screen and join in yourself if you want. There are literally thousands of online chat rooms that you can use, catering for every kind of  interest group under the sun. Many of them relate simply to hobbies or other interests but some are devoted to cybersex. In some BDSM chat-rooms 'sceneing' or cybersex is either permitted or encouraged. What happens, in effect, is that two or more people will construct a shared sexual fantasy, describing how they feel and what they are 'doing' to each other. A bit like an inter-active story. Many people regard cybersex as harmless fantasy because they say its not happening in the 'real world'. Well, thats debatable. There are certainly real people involved. They can  become physically aroused through cybersex. They can form deep and lasting relationships. They can fall in love. They can get hurt. They can break each others hearts. They can change their lives for better or worse. All without ever physically meeting. So where do you draw the line between 'fantasy' and 'reality' ? Its not as clear cut as you might think and thats what gets some people so confused. Lets say that you become devoted to a man who creates D/s scenes with you online that are powerful and sexually exciting. Does that mean he actually has a clue what he's talking about when it comes to the bondage or whipping  that excites you so much ? Not necessarily and in fact not even very likely. All you can really say for sure is that he is imaginative and can type, nothing more. Does that matter ? Not at all unless you ever plan to go from 'cybersex' to a 'real-life' situation where he will actually try to do any of those things to you. Then it could hurt you. Or lets say that you 'explore your sexuality' in cyberspace by giving your submission to a whole succession of men in one-night stands or intense romantic relationships. Then one day you meet, either online or in 'real-life', the real love of your life. Will he think the submission you've given away was just a harmless fantasy or the loss of something irreplaceable ?  There are no absolute answers, but be very careful with cybersex because its more powerful and complex than you might think at first glance. If you ever do manage to work out where the line between 'fantasy' and 'reality' lies, let me know because I'm still trying to work it out.
