The world of fetish is so diverse. What I find so interesting about my own fetishes and tastes are that they constantly evolve and I'm introduced to new ideas and practices all the time.
I find other people's fetishes and sexual practices fascinating. I recently had a conversation with a friend about urethral play which led me on to investigate catheters. These are not to be confused with catheter needles (which is what I thought we were talking about)- Catheters are used in urethral play, which involves inserting objects down your urethra. The most common objects used are sounds which come in various sizes and are usually only inserted about halfway into the glans and can be easily retrieved. Other objects can be used to go deeper and towards the bladder. The urethra is really sensitive and the stimulation of it can cause orgasms, here we take a deeper (pun intended) look at how catheters are used.
Catheters are flexible tubes often used in medical treatment to drain the bladder. Within BDSM, the main use for catheters are for bladder control play- this involves inserting a sterile catheter tube into the urethra all the way down to the bladder with the open end of the catheter emerging at the end of the penis.
A catheter is a great tool in power play dynamics. The dominant partner is essentially in charge of allowing the sub's urine to flow (or not). The stimulation in the urethra seems to trigger the brain's pleasure centre that ordinarily responds to urination or ejaculation. The duel aspect of catheter play is the physical sensation and psychological effect of having an object inserted into the urethra. Often catheters and urethral play is used as part of medical fetish role play. The submissive partner is often restrained and can be gagged, stripped and humiliated while the dominant partner can adopt the role of medical professional and perform 'examinations' and 'tests' which may be painful or humiliating. The loss of this primary function means the sub is at the total mercy of their Dom and the vulnerability/trust can be a massive turn on for both parties involved.
There are several kinds of catheters, usually made from latex and coated with Teflon which makes them very smooth when lubricated. Some catheters are made of plastic which becomes very flexible at body temperature; these are usually little more than simple tubes with a slight 'funnel' at one end. The most common type of catheter preferred for use in play is the Foley catheter. A Foley catheter may be kept in place for a while. Although catheters are often kept in place for days in a hospital, it's recommend that you do not leave it in place for longer than one to two hours while you play.
By removing the catheter syringe, your sub will piss and keep pissing until he's empty- drinking a few pints of water would probably be good prep work. Even when the sub is empty, he will still have the sensation that he's pissing. For subs into piss play you can incorporate this into a recycling game in which the piss is collected into a leg bag, the contents then fed through a drinking tube from the bag.
Safety in all types of BDSM play is so important. With urethral play make sure you are doing your research and playing with someone who has experience. Bacterial infection in the urethra or bladder is the most common danger when using catheters. Symptoms normally develop within a couple of days of catheterization and If you do end up getting an infection, it can be unpleasant but can generally be treated with antibiotics. Make sure all equipment you use is sterile and you're fully recovered before indulging in catheter play again!
