Sex during vaginal infection: Is it harmful?
Medically reviewed on February 21, 2017
Having sex when you have a vaginal infection or vaginal inflammation may be uncomfortable and might make your symptoms worse. If the source of your infection is from a sexually transmitted infection, you may also transmit the infection to your partner. If you have chronic yeast infections (candidiasis), confirmed by a doctor, you may have sex, without concern for worsening symptoms, as long as you're comfortable.
The most common causes of vaginal infection are:
- Yeast infection (candidiasis)
- Bacterial vaginosis
Yeast infections and bacterial vaginosis aren't sexually transmitted infections, but having new sexual partners increases the risk of bacterial vaginosis.
However, trichomoniasis is a sexually transmitted infection. To prevent possible reinfection, wait to have intercourse until you and your partner complete treatment and you no longer have symptoms.
