Just stay and keep things sterile, clean yourself, clean your surroundings and hands that will manipulate things, having something in the bladder is bad, but an infection in the testis will be more complex to manage. If you feel any pain, stop doing it, retract the catheter slowly. Always observe the output of the catheter, don't inject stupid things in your cock, I see this kind of stuff at least once a month.
Keep a phone around you, if you have a problem, explain the ER everything, that's their job, don't keep things for yourself thinking it's gonna be fine, you are doing a form of least invasive surgery on yourself.

Thanks, I like it too, and yes lots of teens and experimenting people are doing it at this age, myself I was playing with my GBA's charging wire when I found out how deep that little hole can go.

>What was injected?
Saline solution

>Seems very medical doing procedures on yourself like this.
I'm a EMT but not a certified urologist. Yes it is about exploring and experimenting.

>You could insert a tube in his urethra and pump sperm directly?
This is very tricky, takes a lot of time to block the bladder with a foley and put the 6fr cath along.

>I'd totally get an appointment to this twink to get my kidney stone removed, would be still cheaper than my health insurance.
In the very worst case I could try flushing the bladder with a 18fr foley but it's not my expertise.
