Bending and twisting of penis after circumcision is very common in clinic, which is caused by irregular growth of foreskin incision after circumcision. If there is no sense of participation, it doesn't matter. It hurts when the urethral orifice touches underwear because the underwear rubs the mucosa of the urethral orifice. It is suggested to wear soft underwear and apply some vaseline oil to the urethral orifice to reduce friction stimulation. Get used to it after a while. I'm a urologist, and this situation is very common. Don't worry. I hope I can help you. You can continue to leave a message if you have any questions.
