14 Signs That Your Partner May Have An STD

Sexually transmitted diseases (STDs) can sometimes show no symptoms at all, making them hard to detect without proper testing. However, there are some signs and behavioral changes that could suggest your partner may have an STD. While these signs aren’t proof, they can be red flags worth paying attention to. Here are 14 hints that your partner might have an STD:

1. Unusual Odors
   Strong or foul smelling genital odors can be a sign of infections like bacterial vaginosis, trichomoniasis, or gonorrhea. If something smells off and it’s not normal for your partner, it might be worth discussing.

2. Itching or Burning
   Frequent scratching, squirming, or complaints about itching or burning—especially after urination or intercourse—can indicate conditions like herpes, chlamydia, or a yeast infection.

3. Rashes or Bumps
   Visible rashes, small blisters, sores, or warts in the genital area or around the mouth can point to herpes, HPV, or syphilis. These often appear during outbreaks and may come and go.

4. Avoidance of Intimacy
   A sudden reluctance to be physically intimate might be caused by fear of transmitting an STD or discomfort from symptoms like pain or irritation.

5. Pain During Sex
   If your partner complains that sex is suddenly painful, especially without any other known medical condition, this could be a sign of pelvic inflammatory disease (PID), herpes, or other STDs.

6. Flu-Like Symptoms
   Fatigue, swollen lymph nodes, body aches, or low-grade fever can occur during the early stages of several STDs, including HIV and syphilis.

7. Discharge Changes
   Unusual discharge, whether it’s thicker, oddly colored, or smells strange, can be a red flag. This applies to both vaginal and penile discharge.

8. Bleeding Between Periods or After Sex
   Unexpected bleeding may indicate an infection or irritation caused by STDs like chlamydia or gonorrhea.

9. Genital Pain or Swelling
   Pain in the testicles, pelvic area, or general swelling in the genital region can sometimes point to an infection that has progressed or spread.

10. Frequent Urination or Discomfort When Urinating
    Burning or stinging sensations when peeing are hallmark signs of many STDs, including chlamydia and gonorrhea.

11. Changes in Mood or Behavior
    If your partner suddenly becomes secretive, defensive, or anxious around discussions of sexual health, it may indicate they’re hiding something or feeling guilty.

12. History of Multiple Partners Without Testing
    If your partner admits to having unprotected sex with multiple people and hasn’t been tested recently, this significantly raises their risk of having an STD, even if they show no symptoms.

13. You Develop Symptoms
    If you begin to experience signs of an STD and you’ve only been with your partner, it’s time for both of you to get tested.

14. They Avoid Getting Tested
    If your partner resists or refuses STD testing, especially if you’ve brought it up more than once, it might be because they fear a positive result or are already aware of a problem.

What You Can Do
None of these signs alone confirm that your partner has an STD, but if you notice more than one and feel uneasy, trust your instincts. The best course of action is to have an honest, judgment-free conversation and encourage both of you to get tested. STD testing is private, often quick, and with our service, available the same day.
