Practice safe sex for vaginal health
Using a male condom or female condom each time you have sex protects against sexually transmitted infections (STIs). Latex and polyurethane condoms prevent viruses that cause STIs from entering the vagina. But, take note, animal skin condoms such as lamb skin will not protect you against viruses, according to WebMD.
Ask your sexual partner(s) to be examined by a doctor and treated if necessary. If you have an infection, avoid any sexual contact with other people until the infection has cleared.
