Causes of Itching or Burning After Sex
In some situations, itching and burning can be a sign of an infection, but not all infections are STIs. It’s worth noting that many of these conditions can cause itching or burning beyond the time frame immediately following intercourse, says Whelihan.
Yeast Infections

While yeast infections can be transmitted via sexual activity, Whelihan says they aren’t considered an STI.[2]

Bacterial Vaginosis
Bacterial vaginosis (BV) occurs when there’s an imbalance of bacteria in the vagina. The cause of BV isn’t well understood, but douching, not using condoms, and having multiple sex partners can increase your risk of developing it.

In cases of recurrent BV, there may be a place for treating the male partner for potential reduced recurrence.Urinary Tract Infection

Treatment typically involves antibiotics prescribed by a healthcare provider.Allergic Reactions

Other common causes of irritation include harsh soaps, personal care wipes, certain over-the-counter products, and generally poor or excessive hygiene practices.“Sweat and friction can cause itching and burning, as well as skin reactions to products like latex or personal lubricant,” says Dr. Malchuk, who adds that topical steroids or allergy pills may be used to treat itching.
Declining Estrogen Levels
[7]
“As people approach menopause, declining estrogen levels can cause itching and burning of the urethra or vagina independent of sexual activity, but sexual activity may make it worse as the tissues become more sensitive,” says Malchuk.
Treatment options can include over-the-counter ointments and creams, low-dose localized estrogen therapy, and other oral or hormone treatments.
STIs
Some STIs can cause itching or burning, although many cause no symptoms at all. The only way to know for sure whether you have an STI is to get tested.

Treatment depends on the type of STI you have. “Often antibiotics or antiviral medication can treat infections,” says Malchuk.
