the vagina has a natural odor. it does not smell like roses you knw. but there are creams like Vagi-Guard or soemthing, sorry forgot the name. But if the smell is really bad or smells fishy, then you probably need to get yourself checked.
most women feel anxious about odor down there. there is nothing to be ashamed of, we all smell in some way. but if the smell is stronger or different from your usual smell then debbie is right, go see a doctor right away.
I like the "does not smell like roses" line! Yeah, the vagina has a distinctive smell and you should not be embarrassed about it. However, a different smell or stronger smell should also alert you to some changes in the vagina that could trigger this. When this happens, its time to go to your doctor! Cheers!
