Chlamydia is the most common sexually-transmitted infection (STI) in the U.S., with over a million new cases reported every year. Chlamydia has been steadily increasing in San Francisco since the mid-1990s.

If you’re having sex, there’s a chance you could get chlamydia. Here’s what to know about what it is, what symptoms to look for, how to prevent it and what to do if you get it.

What is chlamydia?

Chlamydia is a bacterial infection that can happen in your urethra (the tube in your penis), rectum (butt), or throat. It’s caused by the bacteria Chlamydia trachomatis.

How do you get chlamydia?

Chlamydia can be spread by all kinds of sex including oral and anal. It can also be spread by ass play like fisting and fingering. Touching any part of your (or your partner’s) body that is infected with chlamydia and then touching your partner’s (or your) cock or butt can spread chlamydia.

What are the symptoms of chlamydia infection?

Not everyone who has chlamydia will show symptoms, especially if the site of infection is the butt or throat. Symptoms can include a dry or sore throat, itchiness and pain when you poop, or a clear or yellow discharge from your cock and pain when you pee. Throat infections can also cause discharge, but this is less common. Chlamydia symptoms usually take about a week to show up.


A medical practitioner can diagnose chlamydia by swabbing your throat or butt. Urine tests are usually used to test for chlamydia infection in the urethra. At Strut, we routinely check your butt and throat. You’ll probably know if you have an infection in your dick. But just in case, make sure to tell one of our nurses if you are experiencing any of the symptoms above or if one of your partners was recently diagnosed with an STI.

How is chlamydia treated?

We can cure a chlamydia infection with antibiotics. If you had sex while you were infected with chlamydia, your sexual partners should also get tested for chlamydia and treated if they are infected.

How can it be prevented?

You can lower the risk of getting chlamydia by using condoms— they can prevent infection if the entire infected area, for example the cock or ass, is covered. But condoms sometimes don’t cover all infected areas so there’s a chance of still getting or passing on chlamydia even when condoms are used.

HIV and Chlamydia

For men with HIV, getting chlamydia can increase the amount of HIV in their semen—making it more likely that they’ll pass on HIV to a partner if they’re the insertive partner, or top, and they don’t wear a condom.
