Is it possible to have sex with just one other partner and still get Gonorrhea or Chlamydia?

Yes. All it takes to contract an STI is one sexual act with one sexual partner who has the infection. This can be your first sexual act, or just your first sexual act with this partner. If they’ve got the infection and you have unprotected oral, vaginal, or anal sex, you can get it.

The tricky thing about Chlamydia & Gonorrhea is that most people who contract these infections are asymptomatic – they don’t have any symptoms at all! For people who do get symptoms, they can include:

  • painful urination

  • painful ejaculation

  • pelvic pain

  • unusual discharge

It’s also possible to contract Chlamydia or Gonorrhea in the throat through unprotected oral sex. The main symptom is generally a sore throat. Flavored condoms as well as dental dams exist purely for protected oral sex. 

At Teen Clinic, we test for Chlamydia and Gonorrhea with a simple urine sample.  Because Chlamydia is the most frequently reported bacterial STI, we recommend testing after unprotected sex or after sex with a new partner.  We also recommend testing when someone is experiencing symptoms, like itching, bleeding with intercourse, painful ejaculation or burning with urination in males, or unusual discharge.

My boyfriend and I both have sore throats but aren't sick otherwise. We are sexually active and have oral sex sometimes. What do you think we have?

It’s possible you both are experiencing symptoms caused by a Chlamydia or Gonorrhea infection in the throat. These two infections are transmitted through infected semen and vaginal fluids. They are bacteria that can infect the vagina, penis, anus, or throat. More often than not, these infections don't present symptoms, so it’s quite possible for vaginal fluids and/or semen to be infected without symptoms in the penis or vagina specifically.


We recommend getting tested as soon as you can. Teen Clinic provides free and confidential STI testing, including a throat culture that will detect if Chlamydia or Gonorrhea are present. Remember that condoms and dental dams are effective methods for reducing the transmission of STIs during oral sex. You can even get flavored condoms for this purpose-- just don't use them for vaginal or anal sex because they can disrupt the normal balance of bacteria in these areas and cause infections like yeast infections. Until you are tested and treated, abstain for sexual activity or use condoms and/or dental dams.
