Could it be a UTI?: It may be that you have a urinary tract infection (uti). Also called "bladder infections, " these can be caused in sexually active women as bacteria is pushed up into the urethra during sex. Fortunately, they are easily treated with antibiotics. Remember to drink plenty of water, and get up to urinate after having intercourse. See your doctor for an in-person diagnosis, though. Good luck. Lgromkomd.
