A down there smell

So I am honestly so embarrassed to even put this out there but no matter what I do my vagina has this smell. I shave, change soaps, use different underwear fabrics and after a shower my vag smells like musty. Even changing towels frequently. It is so annoying and after a shower my boyfriend wants to do stuff and I just can’t. Any suggestions on what to do? And it’s not like it’s inside of me smelling weird it’s just the hair on the lip part I guess.
