Warm water is all you need unless there’s a severe imbalance (bacterial, yeast, etc) then those need to be addressed medically. Those aren’t fixed with a soap, most of the time it’s fixed with a cream or antibiotics. Our vagina is really good at cleaning itself. If you’re a bigger girl with more adipose tissue down there, then I would look into feminine washes to keep things fresh around your vag. The fat folds and such are not cleaned by our vagina lol.
I personally don’t feel water cuts it for the entire “downstairs” area. I need to clean the labia area/vulva/urethra with a gentle cleanser. But the vagina itself is self-cleaning beyond an infection & don’t douche at all or use any suppositories not prescribed by a doctor because that will be likely to cause one (opposite of what you want). If you’re specifically worrying about taste, pre/probiotics and pineapple.
Could be diet, could also be your underwear. Is it breathable? You might want to switch to cotton. The poor thing has to breathe lol. If you’re choking it out you’ll start to smell some funk. If it smells yeasty/like bread but there’s no itch, it could be diet. If it smells like that and itches it could be a minor yeast infection. What smells are you worried about? If it’s just faint coochie smell with musty sweat then you’re probably not airing her out well enough
If you’re feeling heat and your GYN came out normal, then it’s probably trapped heat from a lack of breathing/airing out. So I’d look into new underwear and see if that helps. Normally if you’re radiating noticeable heat from that spot, it’s an infection of some sort or trapped heat/sweat from activity or bad underwear.
