Vaginal sounds are mainly caused by the front and back walls of the vagina not fitting together, creating a gap that allows air to enter and exit the vagina, which is known clinically as a blowout. This is mainly due to the fact that the pelvic floor muscles are compressed by the dewlap for a long time during delivery, which reduces the tension of the pelvic floor muscles and loosens the vaginal wall, resulting in a gap between the front and back walls of the vagina. Another reason is that the pelvic floor has less fat and the front and back walls of the vagina do not fit together, which can lead to pussy blowing. In clinical treatment, the most important thing is to do anal lifting exercises, and persist for more than half a year, after the tension of pelvic floor muscles is restored, this condition will disappear.
