Hello! Thank you for the query. Such symptoms are very characteristic for urinary tract infection and vaginal infection. Intercourse can be a factor of this infections and some persons do suffer with every intercourse. You may also have frequent urinating and/or burning while urinating. I suggest you to visit your doctor, have vaginal swab test, urine analysis. Antibiotics might be necessary. In the future please try to urinate after intercourse and wash you vagina. You should also start cranberries supplementation and increase mineral water intake. Hope this will help. Regards.
