Built-in tampons are suitable for married women, or women with a history of sexual intercourse can apply, otherwise if a virgin applies a tampon, it is likely to be improperly operated resulting in damage to the hymen, so it is not recommended that women without a history of sexual intercourse apply tampons. The specific application method is to bring a good finger cover, tampon inserted deep into the vagina, put the tail line in the external vaginal opening. After about an hour or so, if you feel that the tampon has absorbed all the menstrual blood, you can gently pull the tampon out by gently pulling on the tail cord. It is important to use tampons during menstruation to keep the area clean in order to avoid infection. In particular, it is important to throw away the finger cots after use and replace them with new ones the next time a tampon is inserted into the vagina, and it is advisable to wash your hands before using them again.
