Experiencing burning after sexual intercourse can be a source of worry and discomfort. Many factors can contribute to this sensation, and one common possibility is a condition known as Bacterial Vaginosis. This bacterial imbalance can disrupt the delicate vaginal environment, leading to various symptoms, including irritation that may become more noticeable after intimacy.
Bacterial Vaginosis and Post-Intercourse Burning
Bacterial Vaginosis (BV) can cause burning or discomfort after intercourse. This occurs because BV involves an overgrowth of certain bacteria, leading to an altered vaginal pH and inflammation of the vaginal tissues. These changes make the vaginal lining more sensitive. The alkaline pH of semen can further disrupt the imbalanced vaginal environment, intensifying burning. Additionally, the natural friction that occurs during intercourse can worsen any pre-existing irritation or inflammation caused by BV.
Understanding Bacterial Vaginosis
Bacterial Vaginosis is a common vaginal condition characterized by an imbalance of naturally occurring bacteria, with an overgrowth of certain anaerobic bacteria and a decrease in beneficial lactobacilli. These lactobacilli produce lactic acid, which helps maintain the vagina’s acidic pH, preventing harmful bacterial growth. While not considered a sexually transmitted infection (STI), sexual activity can influence the vaginal environment and increase the risk. Factors disrupting bacterial balance include douching, new or multiple sexual partners, and certain hygiene products. BV affects about 35% of people with a vagina, making it the most common vaginal problem for individuals aged 15 to 44.
Other Common Symptoms of BV
Beyond burning after intercourse, Bacterial Vaginosis often presents with other symptoms. A characteristic sign is a “fishy” vaginal odor, often more pronounced after sexual activity or during menstruation. This distinct odor indicates bacterial imbalance. Vaginal discharge may change, appearing thin, off-white, gray, or greenish. While some individuals may experience vaginal itching or irritation, many people with BV might not have any symptoms at all. Burning during urination can also accompany BV.
When to Consult a Healthcare Professional
If you experience persistent vaginal burning after intercourse, unusual discharge, or other concerning vaginal symptoms, consult a healthcare professional. Self-diagnosis is not sufficient, as various conditions, including yeast infections or STIs, can present with similar symptoms. A healthcare provider can diagnose BV through a pelvic exam and laboratory tests of vaginal fluid, including pH checks and cell examination. Untreated BV can lead to complications, such as an increased risk of acquiring STIs, pelvic inflammatory disease, and, in pregnant individuals, premature birth. Treatment for BV involves antibiotics, prescribed as oral medication or a vaginal gel or cream; complete the entire course for effective treatment, even if symptoms improve.
