The granularity at the vaginal opening is usually due to the following reasons: 1. The presence of folliculitis. Many women have sensitive skin in their private parts, so if they do not change their underwear or wash their pubic area in time, it is easy for the local follicles to become inflamed, resulting in granularity at the vaginal opening. It is recommended to pay attention to the cleanliness and hygiene of private parts in daily life and keep them dry.2. There are gynecological diseases. If women suffer from vaginitis, vulvodynia, cervicitis, cervical erosion and endometritis, there will be an obvious increase in vaginal discharge. The actual fact is that you can find a lot of people who are not able to get a good deal on this kind of things.
