Frequently touching the vaginal opening with your hands may lead to urinary tract infections in women. Because the urinary and reproductive systems of women’s pubic area are very close to each other, they are prone to cross-infection, especially when the hygiene and cleanliness are not done properly before touching the vaginal opening with hands, it is more likely to lead to bacterial infection and thus cross-infection of vaginitis and UTI. The main symptoms of UTI are frequent urination, urgent urination, painful urination and even blood in the eyes. Therefore, women should pay attention to hygiene and cleanliness when having intercourse or masturbating, especially hand hygiene, to avoid cross-infection of the vagina and urethra.
