Urethral stimulation and catheters

[hehich]

A little preface. For the first time when I became interested in the topic, I tried to introduce a pipette. It is quite thin and very smooth. There was no discomfort either with an erect penis or with a flaccid one. Time passed, the baggage of perversions was gradually replenished and I decided to try a chastity cage. And I came across an interesting option with a special catheter. I googled Russian-language forums and foreign ones, it seems like the topic is safe, the steel is medical, smooth. In general, I bought it, I’m starting to try to enter it, but it doesn’t work. There is a lot of lubricant, plus the penis secretes a lot, everything is wet and slippery, and the catheter barely reaches somewhere in the middle of the penis and that’s it, severe pain begins. Even if you want to, it’s difficult to continue. Then, out of curiosity, I tried the same with a pipette, again everything was perfect. I started studying the catheter and immediately noticed that it was a little thicker (diameter 8mm). Then he began to examine the steel tip of the catheter, moving it over the skin, and it seemed to be a little sharp at the hole. I thought the problem was in the catheter, the device itself doesn’t seem to be particularly expensive ($30), maybe it’s hack work, but then I came across a video where people stick pencils, fingers, and basically everything they have at hand... Now I think, maybe the problem is still in me.
Does it need to be stretched, or maybe there is some kind of hidden disease, I don’t know...

Has anyone encountered something similar? Or maybe someone is just rummaging around for this and can suggest something...

For beginners this is ok. Stretch it slowly. Now I have a 10mm bougie that goes all the way to the bladder. Very cool.

For beginners this is normal. Stretch slowly.

how to stretch? just try to enter regularly? Or do you still need to start with smaller diameters?

Well, of course, start small and don’t forget about hygiene! It’s better not to use it in the urine, it’s not necessary. You need to feel where the buzz is, where the pleasure is, and jerk off in this place. But after that I always rinse the urethra with chlorhegsedine, without fail. And then it hurts to urinate all day.
