Guide to Urethral Sounding

Seatlte Dominatrix Ruby Enraylls Latex Medical Fetish Mistress, Expert on Urethral Sounding

Urethral Sounding is a very popular medfet activity and due to its popularity in videos, its something that many people are curious about. The first question I am always asked is “does it hurt?” The answer should be “no!” As long as you use the appropriate lube, correct angle, adequate technique, good instruments and everything is sanitary- Sounding should NOT be painful. For that matter, catheterization really shouldn’t be either but plastic is harder to work with than metal but I digress. That’s why I threw away all of my silicone sounds.

In my opinion, soft skills like power exchange and humiliation play are much harder to master than hard skills like urethra sounding. This is because there is a simple set of rules and guidelines you can follow to achieve your goal. With soft skills, it gets a bit trickier. Let’s start with what you absolutely need to have in order to actually do urethral sounding- The gear.

The Gear for Urethral Sounding

What Urethral Sounds Should I Buy?

There are many models of sounds. For beginners, I recommend Double Ended Pratt urethra Sounds or Double Ended Hegar urethra sounds.  Rolled steel sounds are best, they are more expensive but they will last longer and you can run them through an autoclave or boil them. Sounds come either millimeters or french for sizing purposes. 1 mm is 3 fr. So a 6mm sound is also an 18fr. Typically sounds come in kits unless you are buying an unusual style but I wouldn’t recommend starting with that.

Individually Packaged Sterile Lube

Why individually packaged surgical lube? Simple. Once you open it, it is no longer sterile. That’s fine for other play but with sounding. You want to maintain as clean of a field as possible. Pretend that you are playing surgeon. When I am doing a sounding scene, I pay attention to order of operations- If there is any butt stuff, that comes last.


Cleaning Your urethral Sounds

The traditional way is boiling them or running them through an autoclave if you have it.
You want to have medical grade sealing sterilization pouches that fit your sounds, pop them in and boil them for at least 20 minutes.
Once they are done cooking, do not remove them from the package until you are ready to use them because you will break the sterile field.
However, many sounds are only coated and not solid pure steel and boiling breaks down the coating. If you aren’t sure of the quality of your sounds or you don’t have sealed medical packets to sterilize your sounds in, wipe them down with a medical grade cleaner like cavicide. However, you need to make absolutely sure to completely remove and clean the disinfectant off before use as it is harmful to humans and even melts plastics! 

Prepping for Urethral Sounding

Always inspect your sounds for any rust, degradation, cracks or rough spots before use. These cosmetic issues can be a home for bacteria or worse, cut your partner’s intimate parts during play. You definitely don’t want that! Before using my sounds,  I make sure that I have grabbed my lube packets, BZK or alcohol wipes and have wiped down a surface to hold all my things. (Medical trays or tables work well.)
If I haven’t used the boiling method, I will wipe my sounds down with alcohol or BZK if they have not been boiled and I repeat the process with my gloves and the urethra. (Pro tip: BZK doesn’t sting. But make sure to check the expiration date on anything you use, including lube.) Allow time for the solution to dry, this is how most sanitizers kill bacteria and viruses.

Beginning with Urethral Sounding

Urethral sounding is pretty straightforward. You want to match the size of the rod to the hole of the urethra, going larger means it won’t fit and too small runs the risk of scratching or puncturing the wall so it has to be just right. You are better going too large than too small though. By holding the tip of a sound near the opening to the urethra, you can guess the size.
In order to sound someone, you want to lubricate the sound, being careful to not allow the open part of the lube packet or the sound to touch other surfaces and once your sound is out of the sterile packet, you cannot set it down or touch past the handle or outside the center (depending on the type.) Don’t worry, this is the most difficult part.

Allow the Weight of the Urethral Sound to Carry it

Once your sound is lubricated, align it with the urethra and allow the weight of the sound to slowly pull it in while you gently hold the base of the penis to prevent bending (if your partner has one.) Be careful to not lose your grip or let go, as you may end up with the sound completely lost (it is retrievable but you want to avoid this.) Ask if there is ANY discomfort, burning, stretching, poking, if it hurts or feels wrong. Also look for any redness, signs of inflammation (redness or swelling,) and of course, bleeding. If all is good, then you’re good to go. Sometimes folks can have a reaction to the lube so it’s good to have a couple brand choices and/or different batch on hand. Or it may just be too inflammatory for someone that day or entirely. Everyone’s body is different and the worst thing you can do with something delicate is force it to happen. Same with fisting.

Now that your sound is comfortably inside, you can glide it in and out! Feel free to experiment with different shapes and types of sounds. One of my favorite shops is The Chain Gang. They have some great guides and typically offer much higher quality toys than you’ll run into on Amazon or your average BDSM shop as they are a specialty store.
Good luck and have fun!

Top 5 Questions Everyone asks a Dominatrix

Seattle Dominatrix Ruby Enraylls in her seattle dungeon with a Slave

Have you ever wondered what your Dominatrix’ favorite bdsm activity is? Or how you can be a better a slave? Perhaps the following can point you in the right direction. Below are my 5 most frequently asked questions and my answers. You might find the questions and their answers a bit surprising. Seattle Dominatrix Ruby Enraylls has the answers to your questions and some tips.

What is your favorite thing to do in a session?

It depends on my connection with the person I’m playing with. Having overlapping interests is important. I’m big on bondage, predicaments and power exchange. I really enjoy mind fucks and getting to be creative. I often tend to get really into a theme for a while. A bit ago it was medical then ADBL, chastity roleplay scenarios, prisoner stuff… it’s always something and my specific interests seem to rotate and shift. I enjoy curating an experience for someone.. The more creative the better. I like longer scenes so I can build up ideas and get to know someone, knowing someone over a longer period of time helps with this as well. Nothing can beat intimate knowledge of the inner workings of someone.

What got you into BDSM and the Femdom lifestyle?

Like many of the people I talk to, I have been kinky for as long as I can remember. If you’ve read my about me, I talk about being kinky when I was pretty young, when it was literally just a game. I don’t see anything wrong with that, although many people I’ve spoken to want to find the reason they are into bdsm. This implies to me that it is something to be fixed when I don’t think that’s true. That’s like saying any preference is inherently wrong. It’s my belief that a homogeneous world is pretty dull, among other things.

But I digress. I’ve always had an interest in Bdsm and the very first adult images I found were femdom related. So it seems normal that I would trend that direction, especially considering that I was raised in a female dominant environment.

Are other people into my fetish?

The shortest answer is yes. I’ve played with many, many people and I can tell you with complete confidence that even if someone hasn’t engaged in your particular fetish, there’s definitely an interest. We live in a kinky world. The biggest barrier to entry is unfortunately, shame.

What do you find attractive in a submissive/slave?

The evil variation of this question is “will you go on a date with me” or worse “can I be your live in slave?” Before asking such questions, consider the one posed above and ask yourself “what do I like most about me?” Personally what I like most about my slaves is that they are considerate, kind and respectful. Every person I notice has a willingness to consider the needs and desires of others and makes an effort to do so. It’s often small things that make the biggest impressions.

What can I do to have the best session with my Domina?

Communicate! Clearly, honestly and respectfully. Sending a long fantasy and play by play isn’t particularly helpful to be completely honest. Writing out a list of yes’s and no’s, hard and soft limits and any specific things you want to try is a great way to start. I prefer to communicate such things at the beginning of the session unless there is something you think I won’t have or something that will need to be prepped for or negotiated. As we get to know each other more, I find that sometimes planning gets a bit more elaborate and more communication before we meet up is necessary or desired.

Scheduling System, Rates, Film Days

Seattle dominatrix ruby enraylls leather boots and gloves

New Scheduling System

I’m delighted to announce that I have added a new scheduling system! This system is only available to those who have completed and passed my intake screening form and those who I have seen before whose contact info I recognize. Once you have completed my form, you will get the login to schedule. If your info doesn’t match info I have, you don’t get to book with me. I am strictly only accepting new inquiries through or with the completion of my form.

Rates (Clarification)

Firstly, my contact and rates pages have been combined. If you’ve been watching my advertisements or my lovely dominatrix website lately I’m sure there’s been a little confusion as to what my rates are. Let me first say, sorry for the confusion and here is some clarification-

Balancing face to face time and what an appropriate risk level is during the pandemic has been a little tricky.

I’ve also been surprisingly swamped with inquiries. Fortunately, I’ve found a solution to that problem, if you’ll see the above (new scheduling system.)

During the last year or so I’ve made some incredible improvements to my dungeon, my bdsm equipment and my dungeon furniture. Prior to my pandemic rate change, I hadn’t raised my rates in years. I think that my improvements are astonishing and well worth the price of entry. You will just have to see for yourself.

Now that I have gotten better organization of my calendar and effective time management, I’ve decided to postpone my October raise but add some other offerings. As per usual, keep abreast of my website, I’m always updating it!

Filming Days

I have very much been enjoying filming with other performers, I hope you have enjoyed my work as well! I’ve discussed with several folks about the prospect of filming together so I wanted to make the formal announcement that I’m going to start offering a “filmed session day”. You will be required to sign a standard model release and provide ID so that I can use the footage but you will be rewarded for it.

Film Days available in 4 hour, 6 hour and 8 hour denominations.

Duos and Moresomes

After Sesta/Fosta was announced, I removed mention of all other people from my site. Since I’ve begun filming with other performers I’ve had folks ask about them and I wanted to answer that question: I absolutely do duos. In fact, I love getting to see you and my friends together! If there’s someone you think is fun or cool, ask us!

Gear Update: Erostek ET312B and Estim 2b

blank

At long last, another gear update! This time… A shocking one. (So punny..) But seriously, I have added the now discontinued Erostek ET312B and the Estim 2B plus a large collection of addons. Everything from CBT, wartenberg wheels, sounds, probes, butt plugs, clips and more! Are you excited yet?

About the ET312B

Erostek is the king of Estim. Their ET312B has been produced since 1999 and has been beloved by kinksters, reproduced, tinkered with and it is a loss that they are no longer in production. If you have the opportunity to get your hands on one like I did, jump on it. With a little luck they may come back into production in some form but if you’ve wanted one, don’t miss your chance. Erostek offers information and parts for current owners. So they are repairable and reliable.

About the 2B Power Pack

The 2B is the only power unit I have used that compares favorably to the venerable ET312B. The 2B’s smaller form factor makes it a great portable that literally jumps to life when powered by the included AC adapter. 

highly recommend this power unit. Those of you who have been following us know this is the first power unit we’ve ever offered by another manufacturer. The 2B caught me by surprise – in a good way. 

– Erostek.com 

Does this mean the 2B is the new king on the electro scene? You’ll have to be the judge.

Comment and tell me what your favorite estim power box and/or attachments are!

The Ultimate Human Toilet Guide for curious toilet slaves

The Ultimate Human Toilet Guide

The Why, the risks and the surprising health benefits to being a human toilet or toilet slave

This is the ultimate Q&A for toilet slaves looking for more knowledge and scat mistresses looking for safety tips (although you should *always* consult your doctor, I consulted one while writing this.)

What is a human toilet?

A human toilet is someone who gets sexual gratification or satisfaction from consuming the feces of another person. There are many psychological components to how this works but it is generally done in a BDSM context.

Many toilets start with drinking their partner’s urine but some also start or end up consuming their feces as well. Occasional a toilet starts out by consuming their own waste out of curiosity; some just start beneath the seat,jumping headfirst into the experience . It’s not uncommon for a toilet fetish to have some cross over with scat fetishistism. This consists of fantasizing about smearing feces on themselves or others. In my experience, it’s common place for toilets to enjoy watching someone go to the bathroom. Fantasizing about the act- Wishing in their hearts they could be underneath. For most toilets the true focus is on feces and not just urine. Being a true complete human toilet usually involves a commitment to the full experience, after all once you are a toilet you may have little choice in the matter. While some people are strongly opposed, which should be respected and discussed ahead of time, many toilets end up accepting both. Although I would say there is some crossover, I would add an additional qualifier to those people or put them in an alternate category altogether.

Why would someone be interested in being a toilet slave?

It is hard sometimes to pinpoint why a fetish is developed and held strongly. Oftentimes it is a combination of things. For some it’s a component of humiliation; being “forced” or degraded to the status of an object meant for waste. For others it’s an intimate act involving consumption of all things that come from their partner. The consumption makes them feel closer, like a form of worship and adoration for their partner. A gift from their partner, being willing to accept anything and take a part of them to nourish their body. In my experience speaking to toilets it is seen as an ultimate taboo to be with another human during the time that they are having a bowel movement. It is an intimate experience. It is seen as “very naughty” to watch someone have a bowel movement. Many were fascinated starting when they were young. Often times it seems like it’s one of those kinks that you were just born with not something that truly develops suddenly., At least that’s been my experience for what it’s worth. Not all toilets have the same desires. Some do not want to consume, some just enjoy watching and feeling as though they are a toilet to be used. Sometimes this means having waste in their mouth, sometimes it means just being under someone going to the bathroom. The point is being part of the intimate act of someone else using the bathroom and feeling as though they are beneath that person. Every toilet’s enjoyment is unique.

Is toilet slavery safe?

All BDSM activity has a risk, some activities have higher risks than others but only you can gauge whether an activity is too high risk for you.
Some risks associated with toilet slavery are bacterial, viral and parasitic infections as well as STI’s and aspiration.

In detail, what are the risks?

Instinctively you might say “getting sick” but what does that actually mean? From my research the biggest risk factors from eating feces relate to the person you are consuming from. This risk comes from bacteria living inside the person and from any disease they might have. Everyone has bacteria that can be either helpful or harmful, there is no negating that risk factor. The good news there is that since everyone’s gut bacteria is different, if you don’t get sick from eating someone’s feces once, it is highly unlikely that you will get sick from consuming that particular person’s feces in the future unless they are ill or acquire a disease.

Any diseases that are passed in feces are a concern. Urine is by and large sterile and not a concern in most cases. The most common serious disease to watch out for is hepatitis. Avoiding people who are unhealthy/currently sick and people who are in living in very unsanitary conditions is a must. It is also worthwhile to exercise caution with someone who has recently visited a country or place where they might have ingested something unsavory such as a tapeworm. If someone is currently sick they can pass that on to you and you can get sick. It is also important also keep in mind that anything they eat/consume will get passed on to you. This can include remnants of food and medications. Be very mindful of who you choose to participate in this activity with. If you have any specific health issues it is a good idea to discuss with your partner. The same goes with urine. (I’ll get your feel wet on the topic of the safety of drinking urine in a different article.)

Full list of Risk Factors:

Bacterial Infections:
In this case it is important to note that most people with a bacterial infection of consequence will appear sick. Symptoms usually include watery and profuse diarrhea occurring multiple times a day. This can be associated with nausea, vomiting, fevers,and abdominal pain. Often times the bowel movement appears “unhealthy” with either blood, mucus, or pus mixed in. Common bacteria of concern include: Cholera, C. difficile, Shigella, Salmonella, Vibro speciess, Pathogenic E coli, Campylobacter Jejuni. It is worth noting that some individuals can be carriers of Salmonella without symptoms. It is very uncommon for this to be the case in the US so the risk is very low. C. Difficile can also be carried without symptoms but is usually not an issue unless you have a weak immune system or have been recently on antibiotics.

Viral Infections:
Most of the viral infections also present with people appearing sick. Symptoms are often times indistinguishable from a bacterial infection aside from nausea and vomiting being more common. Occasionally someone with a viral hepatitis will have jaundice or very dark colored urine. Certain viruses are also associated with “common cold” symptoms. Common viral infections include Hepatitis A and E, Enteroviruses, Norovirus, rotovirus, and polio virus. Most people should have been vaccinated against Polio and Rotovirus. A vaccine for Hepatitis A is available and is reasonable to request from your doctor. If you are concerned you can get titers to prove you are immune through your doctor.

Parasitic Infections:
While parasitic infections do exist, they are incredibly uncommon in otherwise healthy adults in developed countries. While I will not delve into to many details, they include Entameba histolytica, giardia, cryptosporidium, toxoplasma gondii, tape worms, and ascaris. Typically risk factors for acquiring relate to eating and drinking unclean food and water, for example drinking unpurified water from a stream or in a country that might not clean their water as thoroughly. Symptoms can range from minor to more severe. Most parasites can be tested for in your doctor’s office.

Aspiration:
It is also worth noting that as with any other food there is a risk of it going down the wrong pipe. Since feces contains a large quantity of bacteria there is potentially a slightly higher risk of pneumonia if this happens. Make sure you flush properly.

Body Fluids:
As with any intimate encounter their is a risk of exposure to bodily fluids (blood, semen, vaginal secretions). These can carry the commonly sexually transmitted infections. I advise most to discuss these issues with their partners before engaging in any consensual activity and the same applies here.

There are health benefits?
Now that we have talked about the risks involved, let’s talk about what you might not know- that ingesting fecal matter can have some health benefits as well if your partner is carefully selected.

There is an emerging field in medical science that is called the “microbiome”. This relates to the idea that the bacteria that reside in and on us help regulate any number of things in the body. In particular there is research that show certain types of bacteria can influence obesity, cancer, autoimmune disease, and overall health. This even includes things you might not expect such as depression. There are cases where a “transplant” of bacteria can cause fat mice to be skinny, it is worth noting that the bacteria came from fecal matter and is introduced to the new mice via an oral route. The reverse is also true. This has been seen in limited human studies as well. While in most cases there is no agreement yet amongst doctors and scientists as to how this information applies to humans, it suggests that consuming the feces of a healthy happy donor can benefit toilets in a way that keeps them healthy. It also potentially implies that the reverse is true: that an unhealthy partner can pass on some unhealthy traits. As with all activities you want to ensure both you and your partner are healthy. Interestingly enough for one condition, c. difficile, a fecal transplant (usually in the form of pills not direct consumption) can be effective when antibiotics have failed.

Hopefully I’ve presented you with some useful data if you are exploring toilet play and if you are grossed out by toilet play I hope to have humanized the people who are into it. I think all topics no matter how taboo are worth exploring at least once and you should always look into the risk factors before delving in head first, you might be surprised what you discover about yourself when you push yourself a little beyond your comfort zone.
