Hello, thanks for using health care magic. From the symptoms you have described, its most likely that you have a bacterial vaginosis which is infection of your genital tract/vagina with one of the bacteria normally present and most probable Gardnerella sp. Bacterial vaginosis presents with itch and typically fishy ordour which become more present after intercourse. However, with the presents of painful intercourse and painful peeing, associated infections with Trichomoniases and Yeast have to be ruled out. You should visit your doctor for proper examination for a vaginal smear with microscopy, pH, KOH etc for identification of the causative agents. Unprotected intercourse is not the only predisposing factor to infections, douching, hormonal contraception, poor hygiene, could also predisipose you. Best regards and hope this helps. Dr. Achuo
