The main reason for the phenomenon of pussy blowing during menstruation is that the vagina is loose and the front and back walls do not fit together, which causes air to enter the vagina and then to leave the vagina, so pussy blowing occurs. It is advisable to undergo pelvic floor rehabilitation to stimulate the muscles of the pelvic floor to restore their tension to their previous state. This will improve the laxity of the vagina, and the front and back walls will fit together, so that air will not enter again. You can also exercise the pelvic floor muscles in your daily life by lifting the anus for a long time. In addition, if you are too thin, the fat in the pelvic floor is relatively reduced and you will also have pubic blowing.
