Vagina advice

So I feel like it smells down there, especially whenever I’m sweating, like I’m not sure if that’s normal , but it really bothers me. My gynecologist has never told me that I have something. I’m a Virgin. It’s super embarrassing, but one time I asked my bf how I tasted when he ate me out (he was very respectful about it) and he said a little sour. I’m really embarrassed by that and I do NOT want to smell or taste weird ! I drink 2-3 liters of water everyday, sometimes more. I don’t eat healthy as of now. I wash down there EVERYDAY with body soap. I wear a panty liner everyday. PLEASE give me some tips ladies ?! 😣 please don’t judge me , I’m really embarrassed by it!
