Hi, There can be many causes of vaginal burning after intercourse and it is important to be evaluated if any of the symptoms linger. While vaginal burning is something that you shouldn t ignore, it s also not something you need to completely freak out over. It s important to deduce what could be the reason behind it and, if need be, go to your doctor to discuss how to remedy the situation. Yeast and bacterial infections caused by changes in the vaginal pH can cause intercourse to be painful and burn afterwards. It is important to be seen by a health care provider to reassure you if an infection is present or not. Vaginal burning and discomfort can have a lot of different causes. Certain vaginal infections such as vaginal candidiasis, trichomoniasis, and bacterial vaginosis are three infections that cause vaginal burning, itching, and discharge. More than likely you are suffering from vaginal irritation from friction during sex. Anything you do to increase lubrication may help with vaginal irritation after sex. I suggest that you schedule an appointment with your primary care physician or OBGYN whoever you see for your feminine health. He or she can take a more detailed history of your symptoms and perform a thorough physical exam. Hope I have answered your query. Let me know if I can assist you further.
