why does it burn when i have sex

Burning during sex is a common symptom known as dyspareunia and can be caused by multiple factors including lack of lubrication, friction, infections (yeast infection, urinary tract infection, sexually transmitted infections), allergies to condoms or lubricants, hormonal changes leading to vaginal dryness, pelvic floor muscle issues, and nerve irritation. Rough or prolonged sex without enough lubrication can cause irritation and burning. Certain medical conditions like vaginismus or vulvodynia and nerve-related issues can also cause burning pain during or after sex. If the burning sensation is persistent, severe, or accompanied by other symptoms such as unusual discharge, swelling, or pain during urination, seeking medical evaluation is important to identify and treat the underlying cause appropriately.
