Downstairs smell! Does this sound like an infection?

HI so for several years (I'm talking 5 to 6) I've noticed ive had a "smell" downstairs. It's not rank or disgusting--it's not like a pee smell either. Only i can smell it apparently too, so I guess that's good. Kinda a "salty" smell i wanna say?

I've had white stuff between the outer labia that sometimes gets on my underwear. It is NOT excessive than usual (and it's not all the time, just some days my cycle)

But the thing is I've never had problems peeing or any pain or itchiness. It feels normal to me. Does this sound normal?
