Kinky Fun with Urinary Catheters

I use catheters in an awful lot of my videos! Do you want to know more and try catheter play yourself, or have you simply wondered why I like them so much?

My first experience with catheterization

The first time I had a catheter inserted was also the first time I had anything inserted into my urethra- and I fell in love fast.

I was visiting a play partner who was seriously into sounding. First, he talked me through sliding curved Van Buren sounds down his cock and showed me how pleasurable he found it. Then, I climbed into the sling he kept in his spare room and he placed a catheter in my bladder. As my piss gushed out of me and into a bowl on the floor beneath, he lubed up a hand and pushed it into my cunt. Being fisted with a catheter in was an amazing experience. My g-spot was pinned in between the cath and his fist, and every movement was breathtakingly intense.

Types of urinary catheters

I enjoy urinary catheters in many sizes and styles- my stretched urethra means I can fit even the largest ones I’ve found, and I also enjoy very small catheters for some of my cervix penetration shenanigans.

Indwelling catheters are the ones that we often think of first. These are the type that stay in place using a small balloon that inflates inside the bladder. The most common type of indwelling cath is a Foley catheter.

Foley catheters are typically “two way” meaning they have two ports at the external end. One has a small rigid cuff, and is the balloon port, used to attach a needle-less syringe and inflate the retention balloon with sterile water. The other is the urine drainage port, to let it all out. However, you will also sometimes find “three way” Foleys, which have an additional port attached to a third channel running the length of the catheter. This third port is used when putting fluid into the bladder is called for! If you’d like to see a three way Foley in use in a kinky context, I use one in my video “you’d swallow anything from my catheter” (available on ManyVids and on Clips4Sale).

Intermittent catheters (sometimes called straight catheters) are much simpler devices. Because they don’t stay in place in the bladder, they have no retention balloon, so they’re just a simple tube. Typically, these are clear, and stiffer than an indwelling catheter, with a colored plastic port at the external end.

What size is right for you?

Catheters are measured by external diameter, given in “French” units. For example, the package to the right indicates that the catheter inside is 22 French, commonly abbreviated as 22Fr. (If you look closely, this is also a three way Foley!) 3Fr is 1mm, so the 22Fr catheter here has a width of 7 1/3 mm.

For most people, 16Fr is a good size to start with, and should go in easily.

The other number typically provided (for the catheter on the right, it’s 30ml) indicates the capacity of the retention balloon- that’s how much sterile water or saline to fill it with. Generally it’s safe to over-inflate by about 5ml, but ideally you’ll stay fairly close to the amount specified.

Where I buy catheters

Most of the time, I buy catheters from Med-Vet International, a medical and veterinary supply discounter. However, when buying from MVI it helps to have a clear idea of what you’re looking for, because the website doesn’t always have product images or detailed descriptions, and they carry catheters all the way from 30Fr (too large for many urethras that haven’t been stretched) to tomcat-sized. If you’re just getting started, you’ll want to order very carefully- or you may want to choose a supplier with a more limited range of products, intended only for humans.

One supplier with a specific focus on home healthcare, rather than hospital settings, is Allegro Medical. If you don’t mind paying a few dollars more in order to make sure ordering is easy and you’ll have everything you need, I recommend their catheter insertion trays. These insertion trays are available both with and without a catheter included- that’s the main detail you’ll want to check before ordering.

How to insert a catheter

Many kinky activities have no clear analogue outside of kink, but catheterization is a definite exception! Training resources for medical professionals about how to insert catheters are directly applicable to what we do in medical fetish play. While you might choose to leave out some of the steps or supplies shown (for example, most people don’t use fenestrated drapes recreationally) the basic process and precautionary measures will still be applicable.

YouTube has many videos on nursing skills that can be helpful. For example, these are all from the same channel:

(If you visit these YouTube videos, please remember to be courteous- that is not the place to leave comments regarding kinks or sexual interests.)

My blog posts about sounding play in general may also be helpful to you if this will be your first experience with urethral penetration. You might want to read Urethral Sounding Tips for AFAB Folks or take a look at Urethral Sounding Troubleshooting in order to know in advance what to watch out for. After a catheter, it’s common to have the feeling that you need to pee, or a little bit of stinging or sensitivity while pissing, but these feelings should go away in about a day if you’re drinking enough water.

Some things I’ve done with catheters

Combining peehole play with penetrative fucking is an extremely hot idea, but many urethral plugs and sounds aren’t safe to have in place during PIV sex, either because they’re too rigid or because the base isn’t the right shape. On one occasion, I tried having sex with a soft silicone plug in my peehole, thinking that it was squishy enough. This felt great for me, but the unfortunate other participant came out of it with a chafed spot on his penis from where he’d been rubbing against the base of the plug! Foley catheters, because they’re flexible and smooth, are a much better option for combining vaginal sex with urethral stimulation. Using a catheter for this also means that you have the option to have piss freely flowing out! My video “catheter dripping POV sex” (available on ManyVids and on Clips4Sale) demonstrates this idea with a dildo fuck.

Dicks and dildos aren’t the only things that feel fantastic while a catheter is in place! I told the story of being fisted with a catheter in at the beginning of this post, of course. I’ve also tried a variety of vibrators- including sticking the entire head of my hitachi in my cunt!

Catheters are very practically useful for the bladder filling play I like to do! Especially if I’m trying to fill my bladder to its limits, the easiest way is to connect an indwelling catheter to an enema bag or other container that I can position up high, so that gravity lets saline flow into me. That’s what I did in “bladder enema desperate retention” (available on ManyVids and on Clips4Sale) which features a second camera angle to show the enema bag.

Many people like to add a leg bag to their catheter, which creates possibilities for thrilling public play. Would it be exciting to walk down the street and know that nobody around you is aware that you have a bag of your own pee strapped to your leg and you can’t stop your bladder from emptying? Or maybe it’s hotter to think about making someone else do that?

Maybe the simplest reason I’ve used catheters is that they’re a convenient way to introduce others to urethral play. Using disposable supplies means that they don’t have to worry about cleaning practices. It also lets me easily bring enough supplies to a party for multiple people to try, without as much planning ahead. On one memorable occasion, I introduced a new friend to catheters and then fucked her with a strap-on, rubbing the catheter inside her with my silicone cock. Watching her face as she took in the complex sensations was magical!

Other questions about catheters

Here are a few questions people asked as I prepared to write this post, along with a couple of topics of conversations I’ve had in the past.

“Can you use latex catheters that are out of date?”

The expiration date on sterile supplies mostly applies to the packaging. If they still look to be sealed, and they haven’t been stored anywhere damp or anything, I really wouldn’t worry about using them. I use out of date catheters sometimes and haven’t had any problems with them. If latex catheters were several years out of date, or had been stored in the sun, it’s possible that the latex might start to break down. In that case, I’d either toss them out or, at minimum, inspect them to make sure the latex didn’t appear crumbly or brittle.

“What if the inflation valve on a Foley catheter gets blocked and the balloon can’t be deflated?”

I’ve never personally witnessed this, but if it did happen, no worries at all: simply cut off the end of the catheter, and the sterile water or saline in the retention balloon will squirt right out!
