Masturbation during menstruation should be prohibited, as should the use of any erotic toys, even non-penetrative ones. During menstruation, the mouth of the uterus is open, the woman’s body resistance is poor, and the act of masturbation is likely to bring bacteria into the vagina or even the uterus, which can lead to uterine infections. Masturbation during menstruation can also be stimulated by toys, resulting in increased uterine contractions during sexual excitement, resulting in abdominal pain or increased menstruation, prolonged menstrual periods, and even causing gynecological diseases such as endometriosis, which is very bad for your health. Generally speaking, the sexual desire will be reduced during the menstrual period, and even with the sexual desire is recommended to restrain themselves, to wait until the complete end of the menstrual period, and then masturbate with the use of erotic toys under the premise of cleanliness and hygiene.
