Smell down there?

Im embarrassed to post this but I was talking to my friends and they were all saying how their vaginas dont smell of anything and so they dont worry about that when their boyfriends go down on them. I feel like mine does have a smell and now I feel super self conscious. My boyfriend has never said anything about it but Im worried that maybe hes thought this before and is too nice to say anything. Is this normal? Should they have a smell or should they not really smell of anything?
