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!

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!

A Dominatrix Guesses Strangers Kinks (Ruby)

A Dominatrix Guesses Strangers Kinks

Something like six months ago I was in a series couple of videos titled A Dominatrix Guesses Strangers Kinks and Guess My Kink Lineup by Cut. They were created by a Youtube studio called Cut that creates content that creates funny, entertaining, prankish and oddly bias challenging videos. When one of the reps contacted me to do the video, I felt comfortable working with them having had done a couple videos before but I had no idea what to expect this time around nor did I have any idea what would happen as a result of the videos being published.

“Guess My Kink” sounded like a game that I could win, so I was game. What I wasn’t prepared for was the emotional impact it would have on me.

During the filming, we had time to connect with each other but the initial camera time I was very off kilter- I was in a room by myself and had no opportunity to connect with anyone. (Although I did make friends with several people after the fact.) It was unlike any time I had been on set because I had been completely alone prior and didn’t know anyone. I know that was part of the point but it was quite unnerving. Once I stepped on to the set, I had to instantly turn on into my normal mode but it wasn’t quite right.

I often play a game of a dominatrix guesses strangers kinks as a party trick or just as an every day part of my life but when you’re dealing with absolute strangers, under video lighting with cameras rolling it becomes a different game. What if I say something humiliating? What if I reveal too much about other people? What if I sound biased or rude? I became very self conscious and suddenly had no idea where I was standing with regard to other people. Then it hit me, this was the whole point of the creation of the video. Other than myself, everyone just looked like people you might find on the street and on any other given day so do I. People in the BDSM community are just like everyone else and unless you know someone pretty intimately their kinks might surprise you. I knew from watching other Cut videos that creating videos was designed to challenge the viewers but I didn’t realize that I was part of that venture. I consider myself fairly open minded but I suppose you can always be more open minded and considerate of others.

Anyway, I believe that our beliefs (both positive and negative) should be challenged. I hope that you too are given wonderful opportunities to open your mind and explore your biases and thoughts.

Ass Eating Clip: Only My Number 1 Gets my Ass

“You’ve done such a good job!” Says Mistress Ruby to her favorite slave “As a reward, you get to worship my ass today.” Slurp, slurp, slurp goes his lucky tongue between her perky perfect cheeks. “Mmffpphh Yes Mffpphhistress.” he responds. “Good boy.” She purrs back and petting his head before turning to me then snapping coldly, her demeanor suddenly changing. “As for you… You’re in the corner today. That’s what you deserve, isn’t it?” I shake my head, solemnly. I had disappointed my Mistress, which is something I ought never to do.

She sighs. “You’ve disappointed me, you know.” I hang my head in shame, hearing the lapping and wishing I could be so lucky. “I’m sorry, Mistress..” She is ruthless and doesn’t accept my apology, nor should she. “You better keep quiet, you understand? Don’t disturb me.” Slurp, slurp, slurp. That lapping is driving me crazy, I wish I hadn’t been such an idiot. I wish I could have pleased her. Now she is ignoring me and rightly so, her pleasure is all that matters.

She smiles at me almost to torment me says “Listen to the pleasure this slave is getting..” The wet slurping between her cheeks of his tongue is driving me mad while I sit in the corner where I belong, watching with the head hanging. “While you get nothing.” She grins cruelly “Yeah, you’ll do better next time won’t you?” She turns away and ignores me again and I almost can’t stand it. “You please me so much.” She says to her favorite slave. “Later, I’m going to make you my toilet. All those glorious things that come out of your Mistress, they are going to go right into you. What a wonderful honor to receive my gifts.” He moans with delight.

She turns back to me and shrugs “You know, my heels are quite dirty. They could do with being cleaned. I suppose I could make some use of you after all.”

Trampling Clip: Sharp As Nails Part 2

“You may have a future as a shoe salesman after all, that’s far more comfortable!” Mistress Ruby says with a smirk, looking down at the victim beneath her. What a pity, he is writhing in pain under her lethal stilettos. She shrugs, he knew what he was in for when he became her slave. She presses the iconic red sole against his mouth and purrs “Very good,” the words roll off her crimson lips like water downhill “I like the weight of my heel on your face.”

Gracefully and with purpose she lifts her other heel off his chest and momentarily balances on one foot then puts both heels over his mouth. “Your weight is divine.” groans the slave, both in ecstasy and sheer agony. “I know.” coos his Mistress in reply. She knows just how to stroke his buttons, to give him just enough to want more but not too much that he can’t handle it. It’s a perfect balancing act, just like the act they are currently in with her heels digging into his flesh.

Will the slave be hold out or will he fail?
