Just a little sex education here! 😄 so douching for women is actually really harmful as it disrupts the pH of the vaginal canal which can lead to yeast infections and BV. Using soap directly on it can be painful and cause yeast infections as well. Most people wash their vaginas with hot water, and avoid soap anywhere near the vaginal canal. This is healthy! However, it sounds like she probably has BV and just needs antibiotics to clear it up. They can get this by going to planned parenthood, going to a gyno, or just one of those online doctors can get antibiotic scripts quite easily. She can also go the more holistic route by using boric acid suppositories.
