Hi I want to know how I can get rid of this smell that is in between my legs it doesn't happening everyday but it happens a lot. Its like the smell is on my pants between my thighs but when I take my clothes off it's not the same smell coming from my vagina but the smell is bad and i smell it when I sit in a chair, or get up out of the chair, or pretty much anything
