6 STDs that can affect your anus
Gonorrhea is caused by the bacterium Neisseria gonorrhoeae. The disease can be transmitted through any sexual route including anal sex. Despite being a common STD, many people with gonorrhea may not exhibit any symptoms.
Gonorrhea can spread from your genitals to your anus when you wipe after having a bowel movement. Anal infection can cause itching, anal discharge, and pain when passing stools. Other symptoms may differ between men and women.
- Symptoms in women may include pain or burning during urination, bleeding between periods: and abnormal (yellow or bloody) vaginal discharge.
- Symptoms in men may include white, yellowish, or green penile discharge, pain or swelling in the testes, and pain or burning when urinating.
2. Anal herpes
Anal herpes can be caused by either of the two main herpes simplex viruses (HSVs)—herpes simplex virus types 1 and 2. Herpes transmission generally occurs when the infected partner does not have visible lesions. HSV can affect any part of the body but is most commonly seen on the genitals, mouth, or anus.
Anal herpes lesions mainly appear as one or more fluid-filled rashes (vesicles) or small blisters. The rashes typically occur on or around the genitals, anus, or mouth and can lead to anal pain, discharge, itching, and change in bowel habits.

Also called condyloma acuminata, anal warts are caused by human papillomavirus (HPV) infection. HPV infection is the most common STI in the U.S., although many infected people are asymptomatic. It can spread through any sexual contact: anal, vaginal, or oral.
Anal warts are small, typically painless growths in the genital and anal areas. They may cause symptoms such as:
- Swelling or lumps in the anal or genital region
Syphilis can be transmitted through oral, vaginal, and anal sex. Signs and symptoms of the disease may vary depending on its stage (primary, secondary, latent, and tertiary stages):

- Secondary syphilis: Symptoms include fever, rash, and swollen lymph nodes
- Latent syphilis: No signs and symptoms in this stage
- Tertiary syphilis: Most advanced stage with multiple complications related to the heart, brain, and other organs
Chlamydia can be transmitted through oral, vaginal, or anal sex and can affect the vagina, penis, cervix, urethra, anus, eyes, ir throat. It can cause anal pain, discharge, irritation, and bleeding. Other symptoms may include abnormal vaginal bleeding or discharge, painful urination, swollen testicles, and pain during intercourse.
