Hello - I have an embarrassing tale behind my injury. I was on webcam with a woman who was into painplay and I indulged her. I took the inner part of a biro (the ink stick, sealed with glue at the end) and inserted it partially into my urethra (writing end away). After the session, I masturbated and ejaculated with no problem - 20mins later I went to shower and use the toilet, but it hurt an incredible amount to try to urinate - to the point a drop may or may not have reached the end, but the pain caused me to stop
Degree understand your concerns went through your descriptions. I suggest you not to worry much. The pain could be due to inflammation of your urethral opening which is caused due to the insertion you mentioned. The covering area around the tip and urethra are so sensitive and even a small crack can do the damage. Urination will be a problem because urine contains a lot of salts. There is bound to be pain and burning. Still you can and have to urinate. Go ahead without any pretext. Nothing wrong should happen. Wait for around 12 hours and observe again. You can consult a physician if need be. Hope this answers your query. Available for further clarifications. Good luck.
