Saliva as lubricant Yes or No?

I have been doing lots of urethral play sessions on cam lately and I notice people do not really care about hygiene and safety when they use sound on themselves, especially when it comes to lubricating their urethras.


High quality sterile lube is essential for urethral stimulation. The urethra has sensitive lining so it’s important to keep it protected. Inserting toys into the urethra can irritate or even damage the tissue, so lube is essential for keeping things super smooth and gentle during the play.


But I see using saliva as lubricant on cam. Can saliva be used as a lube for urethral play?

In short: NO. You should NEVER use saliva as lube for urethral play. This may seem like a quick idea but it can cause more harm than good. Avoid saliva at all costs if you wish to have safe and enjoyable urethral play experience.


While saliva may work as a lube substitute for certain activities (i.e. masturbation) it is not recommended for more complex activities such as urethral stimulation. 


1.    Saliva dries pretty quickly. Since urethral sounding requires careful and often deep insertion, no one can produce enough saliva to provide lubrication for a urethral toy. All it does is to dry up very quickly and cause friction that leads to burning and it will damage your sensitive urethral tissue.


2.    Another issue with saliva as a lubricant for urethral sounding is that it can cause urinary tract infections. Saliva contains digestive enzymes that break down food. When you introduce these bacteria and enzymes into your urethra, the result can upset your urethral microbiome and leave you susceptible to developing an infection

3.    When playing with your partner - Any STI in the throat or mouth can be transmitted to the genitals through saliva. For example, if your partner has an active herpes lesion for example, using their spit to make things slick could leave you with genital herpes. I will write another blog soon after I finish my research and fact check with medical professionals.


Sterilisation your toy is also important, I wrote a blog a while ago about Urethral Sounding with sterilisation info: https://www.madame-li-ying.com/blog/urethral-sounding

Penile needle play

Needle play is the practice of inserting needles under the skin of the submissive and is considered a form of “Edge Play”, it can produce an intense natural endorphin high which can last for hours. Needle play involves inserting a hypodermic needle into the skin through the at least the top two layers of the skin, epidermis and dermis.


Penile needle play is one of my favourite CBT activity, today I am going to talk about the dos and don’ts. There are specific techniques and precautions in penile needle play and you need to know your penile anatomy well to avoid severe injuries.

This blog is probably more for advanced players than beginners but feel free to read on even if you are new to needle play, I am going to make it easy to understand without boring you with mind numbing details. I will write a blog about basic needle play in a couple of weeks time.



First of all, it is important to know about what skin does:


The skin is the largest organ of the human body, it serves as a barrier to protect the body from the external environment, regulating body temperature, keeping the moisture, excreting waste via sweat and most importantly transmitting sensations to the brain through the nervous system. Skin also hosts a variety of microorganisms.


Skin consists of three major layers: 

·      Epidermis – a comparatively thin layer of skin that lack of blood vessels.

·      Dermis – supplies blood to the epidermis

·      Hypodermis or subcutaneous level – consists of fat cells, blood vessels and nerve endings.


Because the skin both hosts and protects us from so many potentially harmful microorganisms, a break in the skin can provide an opportunity for those organisms to enter the body. Before skin is pierced with a hypodermic needle, it needs to be treated with an antiseptic to lessen the risk of infection.



Skin prep


The two most common antiseptics for play piecing are providone-iodine and isopropyl (rubbing) alcohol. Alcohol is drying to the skin and should not be using on mucus membranes, also it stings if use on broken skin.  Alcohol has a good instantaneous effect on microbes but it is not persistant. Once the skin is pierced, the wound needs to be protected until it can heal well enough to reseal itself.


Providone-iodine (Betadine ©) is another commonly used skin antiseptic in needle play, it does not dry out the skin and is non irritating to mucus membranes.


With Providone-iodine, you need to check with clients whether they are allergic to chlorhexidine before you use it and this can be part of your standard questionnaire. These reactions are very rare, so these same skin prep agents are still used as before in hospitals, they just ask about allergies first. If in doubt you can do a patch test when they arrive, leave it when they are getting ready. If there’s no itching or irritation then go ahead with the skin prep.


Regardless of which antiseptic you choose, do not go over the same area twice with the same antiseptic pad to avoid recontamination. Start to wipe it in the spiral starting from the centre to the outer area, just throw away the used antiseptic pad half way through and start a new one if needed.


Penile anatomy


The parts of the penis are the base, shaft, glans, and foreskin. The tissues that make up the penis include the dorsal nerve, blood vessels, connective tissue, and erectile tissue. The urethra passes from the bladder to the tip of the penis.

(https://visualsonline.cancer.gov/details.cfm?imageid=11321)

  • Glans, the head or tip of your penis
  • Foreskin (if your penis isn’t circumcised, this covers the glans)
  • Shaft, the length of your penis
  • Scrotum, the sac that holds your testicles 


There are arteries inside the penis: 

Dorsal penile arteries

Cavernous arteries (deep arteries of the penis)

Bulbourethral arteries

Circumflex arteries


What to do and what NOT to do:


First and foremost is client’s desires and limits. For novices I focus on epidermis of the shaft and scrotum using 21 - 23G needles and work my way to the glans whenever client is feeling more adventurous. Do not put needles into the shaft i.e. across the Corpus cavernosum and Corpus spongiosum. I have seen many people doing this and THIS IS NOT SAFE!


Corpus cavernosum: Two columns of tissue running along the sides of the penis, blood fills this tissue to cause erection. 


Corpus spongiosum: A column of sponge-like tissue running along the front of the penis and ending at the glans, it fills with blood during an erection, keeping the urethra – which runs through it open. You do not want to stick the needle across the urethra and cause damage. If you go through the shaft arteries breaks there will be heavy bleeding and haematoma which may not be absorbed.


If you are not familiar with penile anatomy, please just stick with sticking needles across the epidermis, nothing will go wrong except a bit of bleeding.

Glans is another safe zone. It is made of erectile tissue but the blood vessels are much smaller (capillaries not arteries) so it won’t bleed as much also blood pressure is not as high.


Scrotum – as long as you don’t stick needles right into the testicles you can put as many needles as you like as long as the client is ok with it.

Client’s care:

I push limits in medical sessions but only with clients whom I am familiar with their bodies and limits/maybes. I communicate a lot in sessions, checking if they are ok. I look into their eyes - if their eyelids starting to drop I have to make sure they are not fainting, I feel their body temperature to make sure their blood pressure is not dropping and they are not going into shock.


It is a good idea to have sweet tea prepared just in case they need it, highly recommend for long hours medical sessions.

Urethral sounding

What is urethral sounding?

Urethral sounding is the insertion of an object into the urethra. They are high polished stainless-steel rods with rounded tips and handles which come in various sizes that are close to one another - differing in diameter by a half a millimetre or less in most cases. There lengths vary from 8 inches to 11 inches depending on their usage and design.


Medically, their purpose is to gently and gradually enlarge the urethra thereby removing any blockages,dilatation of strictures or for obtaining access to the bladder in urological surgery.  

In medical play, urethral sounds are a form of sexual stimulation and exploration for both women and men, and I just realise it is also called “cock-stuffing”. 


Anatomy of urethra

The urethra is a part of the body found on both the male and female genitals. In men, the urethra is around eight inches long, and runs along the length of the penis, through the prostate, and up to the bladder. It carries both urine and semen. In women, the urethra is much shorter, usually being around two inches long. The female urethra connects directly to the bladder, and only carries urine. Both sexes have a urethral sphincter, which allows them to control when urine can exit the body, and men have a second one to restrict urine during ejaculation.

Sound play is not rocket science, it is a deeply satisfying and intense experience if done correctly. However, it is also a sexual activity that brings certain risks.


Hygiene and safety:


Sterilisation: Always sterilise your tools in medical play sessions. If you do not want to invest in an autoclave there are other products such as Virkon and Perasafe which is excellent for sterilisation. I will write another blog about sterilising instruments soon. Rinse item with mineral water after sterilising. Do not use tap water.


As soon as the item is exposed to air it is no longer sterile so sterilise it just before you use it to minimise risk.


Hands and gloves: Scrub your hands with antibacterial soap, don’t forget to scrub your nails. On top of that use individual packed sterile gloves for extra protection. It is important to know that non-sterile gloves (non individual packed latex or nitrile gloves) are typically used for non insertion procedures and examinations i.e. anal play. Sterile gloves are used to carry out insertion procedures such as sounds and catheterisation.


Clean the area: Clean the penis with sterests unisepts especially the external opening of the urethra (meatus) .


Sterile lubricant: Make sure you use lots of lube to help the insertion nice and smooth. Use water based sterile lube sachets. Do not use oil based lube as it is hard to expel afterwards and encourages the build up of microbes and results in infection. Do not use saliva as lube.


Choose the right size: Depends on the sub’s experience. I always start with the appropriate size and work my way up to avoid overstretching the tissue.


Go slow, don’t force: Insertion is one of the most sensitive part of urethral play and it should be done with care. Insert carefully, gently guide the sound into the urethra, don’t force, take your time, be mindful of how your body feels. Stop anytime if there is pain, resistance or “block”. Do not wank the sound in and do not wank when the sound is inside the urethra. I have seen too many people do this, they obviously overlooked the risk of urinary tract infections, tissue damage and false passages. 


You shouldn’t try sounding if:

Any abnormal discharge coming out from the urethra

Outbreak of STDs

Recent UTI

A history of UTIs

Difficulty passing urine

Problems with sounding/catheterisation

Prostate gland enlargement

History of surgical treatment for prostate or bladder cancer

A prostate condition like: prostatitis, benign prostatic hyperplasia or prostate cancer.

Different types of sounds I use in my medical play sessions: 


I always purchase surgical grade stainless steel, titanium or silicone made products. 


Hegar sounds: 


This is technically a uterine sound, rather than a urethral sound. Hegar sound are used to induce cervical dilation in order to gain entry to the interior of the uterus, they are widely used in gynaecology to open up the cervix. 

Hegar sounds are truly a good choice for a beginner who wants to try urethral stretching because of the shape, I start with the second smallest sound in the kit and build the way up from there. 

I use Hegar in most of my medical play sessions.


Rosebud sounds:

Also called Bake or bullet sounds. I like them because they are thin, non-intimidating and relatively short. The tip can be used for targeted stimulation of sensitive urethral spots or it can simply provide additional stimulation to the urethral walls during use.

There are other types of sound I would like to bring into my medical play sessions such as Van Buren and Guyon but I would like to investigate more first.


Hope you enjoy reading my blog. If there is anything you would like me to cover in medical play (within my knowledge) please email me I will consider.
