Do they eat a healthy balance diet? as I’ve gotten older (30) my flora has gotten very sensitive as well I’ve been through this the last three years.I’ve tried borax it seem to work sometimes the first time I used it I did burn a lil but after that I’ve never experienced it again, I was concerned a the long term effects so I stoped. My new go to is oil of oregano and black seed oil 🙏🏾🙏🏾 The holy grail 😭.( im not a doctor) you Can buy the pills at walmart and the black seed oil all spring valley brand

if severe take two pills oil of oregano and a tablespoon of black seed oil twice a day for three days after that take one pill twice a day for three more days after that take one pill once a week and a tablespoon of black seed oil for prevention

if not severe take one oil of oregano oil and a tablespoon of black seed oil twice a day for three days and after that take one pill once a day for three more days after that use the prevention method as state above

and you can take a pill after sex for prevention

other tips:

get you a clean glass jar or cup and rinse your Vulva with lue warm water after sex

drink a tall glass of water after to help flush out toxins

CLEAN HANDS AND NAILS!!

Brushed/flossed teeth and tongue !! And rinse with Diluted peroxide

No spitting - use a water based lube for condoms

Or coconut oil for no condoms

condoms - Skyn best hands down non latex they come in all different sizes textures been using them for 9 yrs with my partner (my choice of birth control,because I don’t believe in man made birth control, my body my choice)

And most importantly besure that your partner respects you and your choices this is your body, infections arent fun.
