A healthy penis should be free of lesions, warts, and abnormal discharge. In general, the penis should be roughly the same color as the surrounding skin, though it may be a shade darker or lighter.
Also, a person should not experience any pain in their penis when urinating or engaging in sexual activity.
A sudden change in the appearance, sensation, or function of the penis may signal an underlying issue that requires medical attention.
This article describes certain lifestyle factors and health conditions that can affect penis health. It also outlines some possible symptoms of poor penis health and provides tips on penis care.
Lifestyle factors that affect penis health
Lifestyle factors that can affect penis health include sexual relationships, weight management, and alcohol use.
The sections below outline some common lifestyle factors that can affect penis health.
Sexually transmitted infections (STIs) can negatively affect penis health. Some of the most common STIs include:
human papillomavirus (HPV)

limiting the number of sexual partners
maintaining a monogamous sexual relationship
abstaining from sexual activity
Often, people who contract an STI do not experience any symptoms. This is why it is important for people who are sexually active to attend regular sexual health screenings.
