I have some black scum like substance under penis foreskin and it smells extremely bad. Is it some kind of std. Can you suggest me some otc meds. It should not be smegma as it is brown or black in colour but smegma is usually white.

Hi Mr. it's developing smegma doesn?t mean you have a sexually transmitted infection or any type of infection. Instead, smegma for both men and women is affected by personal hygiene. Hi the fluids in smegma are released naturally by your body every day. They help lubricate your genitalia and keep the skin from feeling dry or itchy. If these fluids aren?t washed away regularly, they can start to build up. Irregularly washing or not washing your genitalia well can cause the fluids to accumulate and harden. It?s important you wash your penis regularly in order to avoid this buildup.
