can drinking water really make you “taste” or smell better?

i’ve never had an odor or really any scent down there at all, but since giving birth i feel like i smell :/ i haven’t really had any dietary changes. i eat pretty clean (vegan) and drink the same amount of water. should i be drinking more? will it really help? i haven’t let my s/o go down on me because i feel insecure about it ..
