A Note About Language:

Throughout this document I refer to "sterilise" and "sterile". In fact it's just not possible to achieve sterile conditions in a session outside of an operating theatre. However, it is easy to get the levels of bugs low enough that we don't need to worry. These are called "aseptic" conditions. Since most people are unfamiliar with "aseptic", I have used the (incorrect) term "sterile".

I have tried everything in this document (after all, I'm the "model") and have been playing with catheters for over fifteen years with only one nasty event. The document has been reviewed by a doctor and I have made all the changes he asked me to make. He does not endorse the document however. You decide whether or not you want to play with catheters. I hope you will be better informed to make that decision when you've read this document.

Have fun!

Introduction

This document is not a comprehensive guide to the use of catheters as part of a S&M scene. It is a brief guide as to what you need and how you should proceed to ensure the insertion of the catheter is safe; It makes brief suggestions as to some possible activities once the catheter has been inserted and finally there are some "Golden Rules" which all parties to the scene need to be aware of prior to the session or scene starting.

The human body carries hundreds of bugs that don't make us ill. For example the very cleanest arse will be surrounded by bacteria including Pseudomonas and Escheria bacteria. They are not a problem. As long as they stay where they are. If either of these get inside the cock they might cause problems. If they get into the bladder then they can do extensive damage, not only to the bladder but possibly to the kidneys. Escheria is present in most drinking water. This does not matter as it belongs in the gut. It does not belong inside the bladder. The guidelines in this book will minimise the chance of this happening.

As I am into man-to-man sexual activity I've made the assumption throughout that only guys are involved in the scene. I don't know how to catheterize a woman so I have not covered this activity anywhere.

I have been interested in using catheters for many years and I have only had one real problem. That was my own fault. It is possible that a guy can have years of safe, sexy fun using catheters and have no problems at all. Especially if he uses this guide! Many guys may get away many times with getting tap water into the bladder with no hassle, just like me. Then I got a massive infection which wrecked one kidney and could have killed me. When I returned three years later to using catheters I wrote for my Top Man the original draft of what has now become this document. I have had not the hint of any problem since. Please read and remember. It could save you a lot of grief, and peace of mind makes scenes go so much better!

I hope the guide is not too clinical for you. We want to have fun, not play hospitals (or do we?!). I hope I've struck the right balance.

What are catheters?

A catheter is a hollow, open tube designed to be inserted into the body, either to withdraw or drain fluids or to put fluids into the body. Some catheters are designed to do surgery through! In this guide "catheter" means a Foley Male Urinary Catheter.

"Male" because female ones are too short to use on guys. "Urinary" because they are designed to go into the bladder. "Foley" because he designed the clever little system by which the tube stays inside the bladder once it has been inserted (up the cock, obviously). Modern catheters are generally Teflon or PTFE coated to help insertion. They are made of latex, silicon rubber or PVC. I do not advise the use of PVC, they are too stiff.

Foley's system consists of a little balloon near the tip of the tube. It can be inflated with water or air (water's safer) by a very fine second tube that runs down the catheter and connects to a valve at the outside end. This "Luer" valve is attached to a syringe to inflate the balloon. When the syringe is taken away the valve stops the water in the balloon escaping so it stays inflated and the catheter won't slip out.

The tip of the catheter is smooth & rounded so it will go in easily and the main tube opens in holes on the side of the tube. This also makes insertion more comfortable. The holes connect to the funnel arrangement at the other end.

Some guys use catheters that don't have this self-retaining system. These are called plain or "Jacques" catheters and are a total nuisance to use in anything but the shortest of scenes 'cos they have a nasty habit of slipping out all the time (but they are cheap - a fraction of the price you might pay for a Foley.)

Catheters come in various sizes, or French Gauges (FG). Most places stock from size FG14 upwards. (That's about 5mm diameter). I suggest you start a novice with a FG16 (6mm) and if he's OK with that, next time a FG18 (6mm) and then a FG20 (7mm). If you want to work up from there you can but it's really not advisable. Using too fat a tube can lead to incontinence later on and it's not necessary to use a really fat tube to get the sensations desired. Regular use of FG26 (9mm) or anything bigger than this is not recommended. It really is best to try to keep to around FG20-22 as maximum size.

The size of the tube in FG or mm (or both) and the size of the balloon will be printed or stamped on the catheter itself as well as on its packaging. Sometimes this is on the funnel, sometimes it's on the valve. You will need to know the size of the balloon 'cos it must never be over-inflated.

By the way, the only difference between male, female and child catheters is the length! NEVER use a catheter that is too short. Male catheters tend to be 40cm or longer. Unfortunately, this information is not always on the packing or on the catheter itself.

Remember that a catheter is open at both ends! You need to plug it with something if you want to avoid getting in a mess. The best thing for this is a tapered plug or "spigot" designed for the purpose.



Why Catheterize?

Some guys get turned on by having a really, really full bladder - even painfully full. A catheter helps to achieve this by plugging the cock. Also, it can be used to insert fluid into the bladder to make it even more full.

Some guys are turned on when someone else (usually a "Master") is in control of whether they can piss or not. A catheter can be used to control this by blocking it with a small plug or unblocking it. The plug could be replaced by a small tap, for example.

Some guys get turned on by being forced to drink their own piss. A catheter connected to some sort of gag arrangement can achieve this.

Almost every "passive" gay guy loves stimulation of his prostate gland. That's why he likes to get fucked. Being fucked stimulates the prostate gland - on the outside. A catheter stimulates it from the inside as it slides through the middle of the gland!

Basically the possibilities are endless. Not all possibilities are entirely safe.



Risks

A little common sense and some planning and forethought and you can have lots of safe, kinky fun with catheters! However, a moment's rash thinking or disregard of the potential risks of this invasive instrument can give rise to problems. Most of the potential problems are minor but some can be quite major. Also, a moment's panic by whoever is using the catheter can rapidly turn frightening for the "bottom" or "Slave" it's being used on.


Infection

The main risk from using catheters is, of course, infection. The body has poor defences against bugs in the bladder. It doesn't need good defences because, as long as a guy is healthy, his bladder is sterile. Using a catheter is bound to introduce bugs into this sterile place. This is unavoidable but we can take steps to make sure that the number of bugs is as low as we can make it. We can also make sure that certain bugs are not introduced. In particular, the two bugs I mentioned in my introduction which normally live in the arse must not be allowed to get into the bladder.

I knew a guy who occasionally used a catheter and a piece of tube to give himself a piss-enema. In spite of the risk he got away with it many times without incident. Eventually he got a very nasty infection in his bladder which tracked into his balls. Had he been aware of the risks of arse-bugs getting into his bladder I don't think he would have played that game.

Alcohol

Almost everyone I know uses alcohol during piss-sex scenes. It's actually quite useful because of its diuretic (piss-producing) effects. But a word to the wise. Never let someone who is tipsy or drunk catheterize you. If the Top Man becomes too tipsy during a scene, ask if you can remove the catheter yourself, and then do something else. If you never use a code word for anything else, please adopt one for playing with catheters.

Catheterizing is an invasive technique which carries a risk, however slight, of infection or injury. Therefore, someone must keep their wits about them so nothing risky is allowed to happen.

If you've experienced the delights of an alcohol enema, you might think of trying to pour booze down the tube into the bladder. Don't! - it doesn't work (the alcohol is not absorbed) and the potential damage to the bladder wall certainly isn't worth it!

Injury

It's not very likely that you will cause any injury directly by using a catheter. There are two small risks. One is that, during insertion, the tip enters the sperm tube and not the piss tube just after it passes through the prostate. Using correct inserting technique with the cock laying against the skin, pointing to the navel, this cannot happen. If it does happen there will be a lot of pain followed by bleeding when the tube is removed. Don't panic! Everything will normally settle down in a few minutes and there will be no further nasties. To repeat, this cannot happen using correct technique.

The other very minor injury can occur if the balloon bursts inside the bladder. This might leave a slightly ragged edge which can score the piss-tube as the catheter is withdrawn. If you do get a balloon burst, just withdraw the catheter as gently as you can. There might possibly be a little blood from very tiny scratches which will heal very rapidly.

Most injury caused by using catheters is as a result of damage done by aggressive bugs. I cannot stress enough the need to keep the scene clean. This is quite easy even in "dirty" sex scenes!

I'm really not trying to scare you off! What I am trying to do is make you aware of the sort of problems that might await you if you don't know what you are doing. I have had some incredibly horny sessions with tubes up my cock but they were horny only because I knew nothing serious could go wrong. My Top Man knew exactly what he was doing so I'd be safe and he also knew what to do if things did start to go awry. The reassurance that things won't get out of hand enables everyone in the session to relax into it and enjoy it to the full.



What you will need

Absolutely Essential:

Less Essential but Quite a Good Idea:



Forward Planning

Catheter scenes can be pretty spontaneous but there is some advance preparation that needs to be done. Anything you intend to connect to a catheter (tubing, tap, gag, whatever) needs to be immersed in sterilising fluid for half an hour before use. Then rinse it in fresh tap water and shake to dry. This kit can be kept on a tray (also washed in the solution) under a cover of kitchen paper. This arrangement keeps it pretty well bug-free for some hours.

Provided you have a clean "spigot" (the little bung thing that blocks the catheter so it doesn't leak) you can insert the catheter before you (or your slave) sterilises the rest of the kit. This can make the chore of sterilising part of the scene.

Foley catheters are very expensive indeed. You can expect to pay up to £10.00 if you can find them in sex shops and not much less than that from medical suppliers. However, I have seen them as low as £1.00 so shop around. You only need what are called "short term" catheters and these are quite cheap. Officially they can be left in for 18 days so are safe for the duration of any S&M or kinky session.

Owing to the cost of catheters, many guys re-use them, sterilising them using Milton or boiling water after each use. This is OK. Be aware though that both methods weaken the rubber so the balloon will fail at some point (no major hassle). It is, however, important to realise that the catheter needs to be re-sterilised shortly before its next use. I estimate that a single tube can be re-cycled about five times if sterilised after use and before next use again. After that the risk of the balloon bursting gets pretty high.

So, you've organised a session and you're getting ready. What follows is the ideal preparation procedure before the actual catheter session itself starts. (Remember, the catheter itself, if sterile, can be inserted before you do all this if that's how you want to play it. The following assumes it's not in yet):


Getting ready...

The catheter

The syringe - pre-filled with the right amount of clean water

The catheter spigot or plug

The lubricant

"Extras" like tubing, bottles etc, can be placed on some fresh kitchen roll wherever is convenient. Try not to handle too much.

.


Inserting a catheter

OK, the kit is all nice and clean (it won't be sterile but there won't be enough bugs to worry about), the cock is nice and clean and everyone is ready to go ahead:

So here we are, the catheter is in place, the guy is very probably hard by now; what do we do now?

Well, initially, not a lot!. It's best to leave things to settle down for a while. The process is not trauma-free and it's wise to just wait for a couple of minutes to make sure the subject is comfortable - well, as comfortable as a guy with a fat tube up his dick can be!

If at any stage you need to get the catheter out in a hurry, the very fastest way is to cut off the valve where the syringe goes. The balloon will deflate rapidly and you can withdraw the tube. DON'T cut though the main catheter tube.

The above may look pretty complicated on paper. It's really not. After a couple of goes it all becomes, or should become, second nature. Practice makes perfect and all that. If you are a beginner with a guy who is used to being catheterized - why not watch how he does it a couple of times before you try. This will certainly give you an idea of the right timing for him. It will also help give him confidence in you.



Now what?

Once a catheter is correctly inserted it can be used for a number of activities...

Almost certainly at some stage the concept of using the catheter to fill your subject up, rather than empty him, will occur to you. Since healthy piss is sterile, it follows that piss is the perfect stuff to use! When my Top Man wants to fill me up we collect my piss during the earlier part of the session in a large (sterilised) bottle. This sits, sealed, on or near a heater so that the piss stays at about body temperature. An arrangement of tubes is used to connect it to the catheter and all it needs is raising up about four to six feet above the catheter to empty into the bladder.

According to Gray's Anatomy a normal male bladder holds up to about 500ml and the owner will normally empty it when he has about 300ml on board. Some guys can hold more. Filling up a guy's bladder using a catheter can be quite painful for him - especially as you get close to a litre. Let him rest from time to time by stopping the flow or even by allowing some back into the container. Then carry on. He'll take more that way. On a slim guy you can even see him filling up.

It won't surprise you to learn that there's a risk attached to doing this. If the valves where the tubes from the kidneys enter the bladder are weak - then you might be filling up the kidneys too. This will manifest as excruciating pain in the lower back. If this happens stop at once, empty the bladder completely using the catheter and then withdraw it. It's probable that re-filling catheter fun is off limits for that guy from now on.








Bits & Pieces

If you are going to connect catheters to tubing, and thence to gags, bottles, whatever, it's best to use thin tubing rather than the very expensive stuff that is sold for the purpose. Aquarium air tubing is cheap and ideal. Having a narrow bore means that the total amount of piss actually in the tubing at any one time is small. This helps stop it getting cold. Ideally, piss needs to be maintained close to body temperature.

The problem with aquarium air tubing is that it's too fine to fit a catheter or much else. This means you have to improvise some means of adapting the funnel of the catheter down to air tubing. You could buy a proper adaptor at a medical supplier but Boots sell little taps in the wine making department that are a perfect fit into the catheter, and the air tube fits neatly into the other end! Also, many foot-pumps for car tyres come with an adaptor for blowing up air beds. This too does the job! You may need to get the air tubing very hot in hot water to make it stretchy enough, but persevere. You only do it once!
