Here is the translation of the provided text into English: Ulcers on the inside of the foreskin sometimes itchy, is this a sexually transmitted disease?

Patient's question:

I am a patient with phimosis and I have never had a circumcision. When I take a bath, I also don't pull back my foreskin to wash it. But recently, I noticed that when I retract my foreskin, there is some white discharge. The inside of my foreskin has ulcers and sometimes it itches. Is this a sexually transmitted disease?

Doctor's answer:

It is an inflammatory response caused by the long-term stimulation of smegma. If you have phimosis or excessive foreskin, it is recommended that you consider timely surgical removal of the excess foreskin, develop good hygiene habits, and actively clean the glans to avoid further irritation from inflammation. Additionally, during the treatment of male urological diseases, the patient's dietary condition and care are also very important. The patient must ensure adequate vitamin intake, prevent stomach issues, and maintain a light diet to avoid unnecessary harm.
