This might help 1.try washing the external part with warm water and unscented soap ( soaps with scent can cause irritation so avoid them) 2. Don't try to wash the inside cause it cleanse itself 3. If you are having sex practice it in a safe way like use condom. If the odor came after you had sex it may not but also it might be STIs so you gotta visit a doctor. 4. This may not be for all but some people notice odor change while using garlic and onion. Try to reduce using them in your diet and see if there is any change 5. If you workout, change your clothes as soon as possible because sweat can create good environment for bacterial growth If this doesn't work you gotta go and see a doctor cause it might be yeast infection or bacterial vaginosis
