Studies have shown that some women only have sex drive during their periods because women have the lowest levels of estrogen and relatively high levels of androgens that produce sex drive during menstruation, which naturally creates the desire to roll with the punches. It is a common understanding that immunity is low during menstruation and that you are prone to illness. According to the NHS, it is possible to have sex during menstruation. Human immunity is influenced by genetics, diet, sleep, exercise, stress and other factors. Menstruation itself does not cause a decrease in immunity. Does menstruation arise in the uterus and not the vagina? The inside of the uterus is tightly closed, and the inside of the uterus is out of reach of guys. So there is no need to worry about the uterus getting hurt. There are also benefits to snapping during menstruation. The vaginal walls are usually more lubricated, and the vulva and pelvic congestion will also make the girl more sensitive and easier to reach orgasm; the endorphins produced during orgasm have the effect of making people mentally happy and some pain relief. I do not encourage snapping during the menstrual period, but it is possible to snap during the menstrual period. The point is to do a good job of cleaning and bringing condoms.
