A normal woman’s vagina is just bumpy, not flat and smooth. The walls of a woman’s vagina are not flat and smooth; there are many vaginal folds on the surface that make it uneven to the touch. These folds make the vagina very elastic and can expand the area into a birth canal during labor, which facilitates the delivery of the fetus. Vaginal folds also tend to harbor bacteria or other pathogenic microorganisms, which can lead to an increased likelihood of vaginitis. Therefore, daily cleansing is recommended to avoid bacterial buildup of infections that can lead to vaginitis. If there is proliferation of vaginal organisms, abnormal leukorrhea, or vaginal redness, swelling, and pain, which suggests vaginitis, you should abstain from having sex and go to the hospital for timely examination and treatment.
