Tingling in the vulva after sexual intercourse may be due to vulvovaginitis or vaginitis. Vulvovaginitis, as the name suggests, is an inflammation confined to the vulva. Common triggers of vulvovaginitis include the use of unclean sanitary products, the stimulation of sex, or the stimulation of menstrual blood. Clinical manifestations include inflammation confined to the vulva, localized tingling and itching, and redness and swelling of the vulva or a rash when examined. The pathogen of vaginitis is in the vagina, the typical clinical symptoms of vaginitis are not only the itching and tingling of the vulva, but more importantly, it is often accompanied by changes in leukorrhea, such as leukorrhea increase, high volume, yellowish-green or yellow, and in some cases, tofu dregs. Whether vulvitis or vaginitis is the cause of vulvar tingling can be determined by a gynecological examination. If there is a combination of changes in the leukorrhea, a lab test can be taken to help diagnose the problem.
