Male sex organs are mostly outside the body (the genitals). This makes signs of certain STDs (sexually transmitted diseases) easier to spot. But STDs can also spread inside the body and damage the organs that allow you to father a child. This damage can sometimes cause sterility—meaning you won’t be able to have kids. Also, men may have fewer symptoms of STDs than women. So pay attention to your body. Learn what’s normal for you, and have any symptoms checked out.
In men, symptoms of an STD are often outside the body. But problems can happen inside, too. Common symptoms may include:
Discharge (fluid) or a drip from the penis or rectum. This can be yellow, white, green, or clear.
Burning or pain during urination.
Sores or blisters on or around the mouth, genitals, or rectum.
Lumps or bumps on the genitals.
Itching on or around the genitals.
Pain in the genitals or rectum.
Keep in mind: You may not have any symptoms. So get checked if you’re at risk of STDs.
