Inserting a catheter
“Catheter insertion” was written for BDSMforyou.nl by Mistress Moriah.
As part of medical play, one may choose to insert a catheter. It is somewhat similar to sounding, but instead of using sounds, a flexible tube is used that ends in the bladder.

What is a catheter?
A catheter is a thin, flexible tube that is inserted into the body to administer or drain fluids. It is often used in medical settings to empty the bladder in patients who cannot urinate on their own, to administer medications directly into the bloodstream, or for other diagnostic and therapeutic purposes. Catheters are also sometimes used in BDSM.
What is catheterization?
Catheterization is the insertion of a catheter or probe into the urethra. The difference between a catheter and a probe is: You can imagine that the urethra is more likely to be damaged when inserting a probe, because it is not as flexible as a catheter.
- Catheter is a flexible plastic tube
- Sonde is a rigid tube (usually) made of metal
Insert the catheter carefully
Like many forms of play within BDSM, catheterization is not without risk. You can imagine that when you insert something through the urethra into the bladder, bacteria can always be introduced into the bladder. This can result in a bladder infection or urinary tract infection. Always be aware of this and therefore practice the highest possible standards of hygiene.
Inserting a catheter requires some (medical) expertise; if you’re inexperienced, it’s best not to attempt this, as you could cause injury. Incidentally, catheters were already used by the ancient Greeks, who emptied the bladder using a hollow metal tube inserted through the urethra. Later, the term came to refer to the device used to drain or administer fluids. It is usually a thin, flexible tube made of PVC or latex. However, larger and stiffer versions also exist.
Safety Tips
- Use only sterile catheters (from a pharmacy or medical supply store)
- Make sure your hands are clean and/or wear latex gloves
- Use sterile lubricant
- Always start with a small catheter and insert it gently
- Never reuse a catheter and never share it with anyone else
Afterward
Afterward, it is important for the sub to drink plenty of water to flush everything out properly. He may experience a burning sensation. This is normal. The urethra heals quickly, so this sensation should subside soon. If this is not the case or if there is blood in the urine, it is advisable to contact the family doctor. This could indicate an infection.
The Experience
The experience for the sub varies and can consist of several elements:
- The Mistress’s complete focus is on his cock
- His cock is penetrated (just like with sounding), which can be experienced as arousing
- The Mistress has control and power over his bladder
Women and catheters
Because the urethra is much shorter in women than in men, the risk of infection is higher. Inserting a catheter (or sounding) is therefore not recommended for women without a medical necessity and “just for fun.”
