If something smells fishy, a half bottle of cheap perfume only makes it worse.
HEALTH Viewer discretion: Ladies, can we speak privately for a moment? Bacterial vaginosis is not deadly, not contagious but, unfortunately, not pleasant — for the sufferer nor those nearby with functioning nasal passages. In fact, crossing one's fingers while attempting to mask malodor with perfume can literally take the breath away from neighboring asthma sufferers  or make migraine sufferers think they are experiencing a gustatory aura. 
Women are taught from an early age to keep their legs crossed. It keeps curious pre-pubescent boys from discovering the shocking differences of their female counterparts. Leg crossing when sitting also trains young women to prevent inappropriate exposure to what's percolating inside at different times during the month.
What is bacterial vaginosis? The human body is actually full of bacteria (flora) — some good and some bad. Bacterial vaginosis results from overgrowth of normal bacteria in the vagina. A foul smelling discharge, affecting 29 percent of U.S. women, is the most recognized symptom. Some women experience a fishy smelling thin, grayish white or yellowish vaginal discharge that is more noticeable following copulation. 
The scent is somewhat different from another common infection. With a nonspecific "yeasty odor," a vaginal yeast infection can produce a substantial white discharge with bits of solid white cotton-like material. This may be accompanied by intense itching. A vaginal yeast infection often results from contaminating the vagina with fecal matter during intercourse or reverse directional wiping when visiting the toilet. (Always wipe from front to back.) Diarrhetic splashing has also been known to cause contamination. A slimy yellowish-green vaginal discharge could be a sexually transmitted disease called trichomonas vaginalis.  (The three conditions along with others are illustrated and described on the accompanying poster, Common Gynecological Disorders.
Having bacterial vaginosis can increase a woman's susceptibility to HIV infection if she is exposed to the HIV virus. It can also increase a woman's susceptibility to other STDs, such as herpes simplex virus (HSV), chlamydia, and gonorrhea. 
Keep It Pleasant
Though bacterial vaginosis is the most common gynecological disorder, researchers are uncertain about what causes it. The condition is often present among women with multiple sex partners, those who smoke or those that douche regularly.  Hence, opposite behavior would seem to minimize the odds.
Women like to be told they smell nice — like flowers even. Cologne and perfume manufacturers bank on it. But combining two powerful aromas nets an overwhelmingly odoriferous concoction. Therefore, masking is, at best, a temporary solution. Don't wait for someone else to bring the embarrassing miasma to your attention. It's not exactly what writer Giovanni Arpino nor actor Al Pacino had in mind with Scent of a Woman. 
Quickly getting to the root of the problem is the best solution. Though there are over-the-counter preparations for yeast infections, bacterial vaginosis is generally controlled with a prescribed antibiotic. This is done following lab results, so don't cross your fingers and hope your fetor will dissipate unaided or that no one else notices. Visit your gynecologist regularly and report any unusual symptoms for treatment.
