Nobody should be spraying perfume on their pussy! If it's alcohol-based it'll burn like a bitch, and all the other chemicals will mess things up... What kind of vagina-owners have you been encountering on your voyage?!
The vagina has a PH that needs to be balanced. If it's not balanced you get a fishy odor. A natural cure for this I've read is to put a piece of garlic in your vagina! Sounds nasty but it works!
