My vag tastes like onions πŸ˜³πŸ˜žπŸ˜‘

I'm a very clean person... I shower daily and sometimes twice. I wash my vagina with vagisil pH balance. It really doesn't smell... and it doesn't smell like onions but it tastes that way... It's a little embarrassing... My husband enjoys going down but not so much on the "flavor" and then we kiss I can taste it too. It's really embarrassing and was wondering if anyone else has this problem? Or have had it and found a solution to the problem?Β 
I don't really have a diet that consists of onions everyday... Sure on occasion I might eat something with onions but not that often.Β 
Signed,
Embarrassed just want a "normal" flavored vagina lol (yes I realize everyone tastes different but onions isn't a flavor I want πŸ˜–)
***UPDATE****
I don't douche never done that. My husbands breath isn't the problem... It's just when he goes down it's like that. Thank you all for your feed back... I will definitely try some of this out... The only one I'm a little unsure about is the water only washing... I know the vagina is self cleaning... That's the inside I never wash inside my vagina just the outside... Which is technically called the vulva the vagina is actually the canal itself. I know not to use regular soap on it but vagisil is a mild soap... I feel if I only used water it'd be smelly then... As I've said I don't smell bad just the taste... I know that's weird but it's just the way it is. So I will be trying some of your suggestions... thanks!!
