Poor hygiene or an infection. but some people have a natural odor. It could also be what you eat or medication or vitamins.

In a healthy, non-infected woman, the vagina shouldn't "stink" at all...that it a marketing ploy started by companies like Johnson & Johnson in order to sell people products they don't need.

the biggest cause: bad hygiene!!!!! also, a poor diet doesn't help. washing every day with soap and water and cleaning in thoroughly in between folds and skin is VERY important. it shouldn't really smell at all....should be pretty much odorless.

Well sounding repetative here but its true.there are so many things now-a-days that can be a contributing facor to a smelly private part. 1) what you consume: the food you eat daily has alot to do with what comes out of your body.Face it, we are what we eat.Your body has various ways of excreting waste and unwanted products.One such way is by the pores in the skin.similarly,the vagina excretes waste products from the body too and if you routinely consume bad things and non-contriuting foods,it is going to be a foul experience. 2) An infection: Yes, most commonly, if you have say a common yeast or just any venereal infection you can expect to have an odor.You could pick up a small kit at any pharmacy like walgreens which allows you to do a simple 1 step home testing to see if you have an infection.It does not,however,tell you which infetion you have so if it says you do have one it may be time to see your doctor. 3)Not showering often enough: Being a healthy woman,you should take a shower at least once every day putting aside exceptions.If you can afford it,twice is even better:it can only do you good.Use scent-free soap and if you use a body wash do not use it down there as these body washes tend to allow for a yeast infection.You could always pick up a body wash that is made for sensitive skin...this can be sparingly used down there to wash away the excess of sweat accumulated. 4) If you have unprotected sex with your partner,his ejaculation mixed with your orgasm fluid is not such a good thing to leave for a long time.Being healthy,again,will buy you some time to perhaps sleep it off or get you somewhat through the day but do not think that having sex tonight then going out tomorrow without showering is an OK thing. Take these and more into consideration as I hope my answers were of a helpful nature. Sue,19 New Jersey.

Its natural just like arm pits

You gotta wash it, it has to be clean. Not by douching everyday, because it has a natural way to cleanse itself. After you period is a good time to douche.

Depents on the intakes, poor hygen, infection
