Hygiene when inserting an erotic device into the urethra

The urinary tract is sensitive to hygiene. This is doubly true for women due to the shorter length of the urethra. After use, rinse intimate areas and toys properly with warm water or disinfect toys with ethanol (alcohol from the pharmacy). With a good wash or wipe, you can get away without the recommended gloves and disinfectant. Inadequate hygiene can result in inflammation. This is manifested, among other things, by the urge to urinate even with an empty bladder, in men also by yellowish discharge or lumpy semen. For treatment, it is usually necessary to see a doctor and to take antibiotics.
It does not pay to introduce into the urethra and at the same time other things into the rectum. Impurities can then only be avoided with great care and are easily carried into the urinary tract. 

Avoid insertion into the urethra if you are going to be travelling, sleeping on the ground or in a cold environment for the next few days. Have dried cranberries ready. They repel inflammation-forming bacteria from attaching to the urethral wall.

Have dried cranberries ready. Incipient inflammation can be treated at home with cranberries and chamomile. You can tell by the colour of the semen. With advanced inflammation, it no longer burns when you urinate and at this stage, natural treatments for urinary tract inflammation usually don't work (but still provide relief) and you need to be prescribed antibiotics. The more experienced ones already recognize this stage and have antibiotics already prepared at home as a precaution. When inflammation occurs, prefer to consume acidic and unsweetened foods and drinks.

Susceptibility of the urethra to injury by an inserted object

The urethral mucosa is very susceptible to mechanical injuries. Inserting, filling and any activity at all may push, but it must not hurt! When it hurts, you bleed slightly (drops of blood or light discoloration at the end of urination) and it only cuts you when you urinate (as opposed to inflammation, which is more itchy). This indicates a tear in the mucous membrane, which will heal in about 2-3 days. Scarring after more damage can narrow the urethra and make it difficult to urinate. It is necessary to proceed slowly. If pain, allow to heal before dilating again. A little pain is part of it, but also a limit that signals a mistake and the need to cut back. In the long run, the less pain, the faster the shift in the size of the mastered objects. When introducing into the urethra, it is not advisable to masturbate, or to be very careful or soften the diameter of the dilator. The mucous membrane is extremely stressed during masturbation with the dilator and injuries occur. There are basically 2 types of injuries. Less painful at the entrance to the urethra and more painful inside the urethra. Injury at the entrance is usually caused by too large a dilator and injury inside by insufficient lubrication (see below) or, in men, by careless masturbation with a urethral device. Particular caution should be exercised by people over the age of 40, who are much less likely to heal from ice than younger people.

Erotic toys for urethral erotic play

The object must be absolutely smooth. The slightest rough edge hurts (for example, the entry holes of common poor-quality hospital catheters). urethral dilators stainless steel. Metal is also more hostile to bacteria. Plastic is less hygienic, glass can break. For catheters, check the roundness of the urine entry hole and briefly apply to the skin and mucous membranes a few dozen minutes before use to test for possible allergic reaction of the body. For plain metal dilators, the following will suffice gels. Ordinary gel does not lubricate the urethra sufficiently, also because it is difficult to get it deeper into the tube. Lubricant should also be introduced by injection with a syringe (without a needle, of course). You can strengthen the lubrication with a cream based on artificial fat and medicated vaseline (e.g. deer tallow without perfume). It will do a good service. Insert the piece into the urethral inlet and push it in with the dilator so that it pushes its way through to the bladder. You can inject drinking water and saline (water, 0.9% NaCl) or even your own urine. Urethral set is also suitable for beginners. Advanced users can also try a hollow dilator with a cavity for urination for more hours. The length of up to 10 cm will allow concealed wear under clothing (not suitable for environments where there is a risk of falling or hitting). There are also urethral dilators with a ring or loop to prevent spontaneous fall out.

TIP: Silicone dilators or latex catheters are less smooth than metal. Therefore, with the exception of catheters, vibrating and inflatable urethral dilators, we do not sell them.

Catheter bladder filling - important procedure and choice of catheter

Catheter filling the bladder is the most advanced and extreme urethral sex game. All you need is clean drinking water. It is important to choose a good catheter. Hospital catheters usually have a main tube for urine or injected fluid and sometimes an auxiliary tube to inflate the end of the catheter so that it does not slip out of the body. The balloon is inflated with water (ideally sterile water) with a small syringe (50 ml) according to the volume prescribed on the package. Fill the bladder with a large 150-250ml syringe. The catheter is usually supplied with a plug to prevent leakage of urine when the catheter is inserted.

All of the certified hospital catheters we have tested (Unomedical a Curity), have a sharp side opening for urine to enter. This opening cuts and injures the external and internal sphincter of the urethra during insertion and withdrawal. Regardless of whether the hole in the catheter is cut mechanically or with a laser, and regardless of the material and coating of the catheter. It is ideal for filling the bladder for the above reasons a silicone catheter with a front and not a side opening for urine entry.

This catheter is more expensive but does not injure or minimizes the risk of injury. The difference in sparing of tissue and sphincters is really extreme. A hospital catheter will always hurt you painfully, so it is always a painless alternative silicone catheter we will no longer offer. The silicone should be able to withstand some 300 °C and can be sterilised by boiling repeatedly without any problems. Therefore, choose a catheter with a narrow diameter, ideally 4-6m (straight bore catheter, see below, can be thicker), which is sufficient for any urine flow or any filling of the bladder with water. The weakest catheters are 3mm diameter and the strongest catheters are 12mm diameter. The thicker the catheter, the larger the opening for urine entry. It's not just the width of the catheter itself, but also the fact that the urethral sphincters can shrink sharply as the catheter is inserted and withdrawn without you being able to affect it with your will. And during this shrinkage, the tissue of your urethra is cut by the sharp edges of the urine entry hole. Thus, the risk of injury to the urethral lining increases exponentially, not in direct proportion, with the size of the regular hospital catheter.

With the preparation above, you can insert a catheter connected to a larger injection and inject water into the bladder or, conversely, suction it. The bladder of an adult can handle about 0.5-0.7l of fluid, but at half full we already feel a strong urge to urinate. The last 10% of its limit is reliably recognized by pain. If you pull the catheter out when the bladder is full, the pressure of the fluid in the bladder will rapidly tighten the urethral sphincters just as you pull the end of the catheter through them - i.e. the sharp opening for the urine to enter and the catheter will painfully cut into your sphincter (this does not apply to a catheter with a direct opening for urine, which can be pushed out immediately). Therefore (before removing the catheter from the filled bladder) first let some of the fluid drain out - e.g. a third or half of the fluid through the catheter to relieve pressure on the sphincter.

Then remove the catheter. And only after removing the catheter, let the rest of the fluid drain out. This is important in order to swell any gels and residues of loose urethral tissue or blood that would otherwise support the attachment and multiplication of bacteria. Be sure not to delay urination. Urinating after catheter removal may cut for several hours depending on the delicacy of catheter insertion and removal, but the sooner you disinfect the urinary tract by urinating, the better. In the hours following catheter removal, it is advisable to drink and urinate well.

Can my bladder burst, What happens when my bladder fills over the limit?

Normally, the body does not allow the bladder to burst. A man pees himself. The exceptions are extreme situations such as bumps, enlarged prostate in men or just preventing urine excretion e.g. by a closed catheter. You don't even get over the limit when filling the bladder with a catheter because of the pain. But in a really extreme situation, if someone else fills you and does not respect your extreme pain, in other words hurts you extremely, in addition to tissue damage from excessive pressure, urine can leak back into the kidneys and damage the kidneys and possibly other organs.

Medical perspective with urethral sex play

Urologists consider these practices dangerous with the possibility of inflammation of the urinary tract and, in the worst case, the kidneys. Skilled urethral dilation can also have a positive effect for people with a narrowed urethra and is also performed as a medical procedure. A narrowed tube can restrict urine output, resulting in inadequate bladder emptying and the need to urinate more frequently.

30 years of experience with urethral shunts

I started out at about 13 with a handle of knitting needles and needles. I now insert dilators a few times a week, catheter exceptionally a couple of times a year. I have had cystitis 3 times which I would not have otherwise as I don't suffer from it. Especially with the lack of hygiene - a combination of urethral and anal play. The occasional pain and bleeding tissue damage subsided within a few hours or a day. I neglect hygiene considerably compared to hospital procedures (no gloves or disinfectant), only washing toys and tissues well with soap and water. I reuse a disposable catheter for several years and wash it only with clean water and soap. I have had no other or permanent problems and have not.
