The condition that is associated with odor is most likely Bacterial Vaginosis (BV), or nonspecific vaginitis. Symptoms include Vaginal odor (the most common, and often initial, symptom of BV); often recognized only after sexual intercourse, mildly to moderately increased vaginal discharge, vulvar irritation (less common) and dysuria or dyspareunia (rare). This is not a sexually transmitted disease and the diagnosis is made by physican examination and on microscopic examination of the discharge or vaginal secretions to look for what we call clue cells. Treatment is easy once diagnosis is confirmed. The other possibility is trichomonas vaginitis which is a sexually transmitted disease and also requires examination and smear to confirm the diagnosis before any final decision is made.
