Teens: STI Symptoms in Men

Male sex organs are mostly outside the body (the genitals). This makes signs of certain STIs (sexually transmitted infections) easier to spot. STIs are also known as STDs (sexually transmitted diseases). But STIs can also infect the mouth and anus and 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 STIs than women. Viral causes of STIs include hepatitis B, herpes, HIV and human papilloma virus (HPV). Bacterial causes include chlamydia, gonorrhea and syphilis.So pay attention to your body. Learn what’s normal for you, and have any symptoms checked out. STIs can only be completely prevented by not having sex. Proper use of condoms (male or female) will prevent STIs but not completely.

What are the symptoms of STDs?

Common symptoms may include:

  • Discharge (fluid) or a drip from the penis or rectum, which can be yellow, white, green, or clear

  • Burning, pain, or bleeding during urination or while having a bowel movement

  • Sores, warts or blisters on, in or around the mouth, genitals, or rectum

  • Lumps or bumps on the genitals

  • Itching on or around the genitals or rectum

  • 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.
