Is this normal when he goes down on you??

Be

So I’ve always been self conscious about my vagina and her smell... it’s nothing you can smell standing next to me but I just notice it from masterbating. I’ve only ever been intimate with my husband and when he goes down on me... he just reeks after of onion/fish. It makes me sooo self conscious. Like so much so I limit how much he goes down on me (which I truly do love). Could I have Bacterial Vaginitis? I don’t have itching or burning... but there is an odor up close :(

Is it normal for your partners mouth to smell like your 😺 afterward? What do they usually smell like to you?
