The phenomenon of blowing during sex is mainly caused by the looseness of the vaginal wall. When the penis is pumped, the air is expelled from the vagina and a loud sound is made. The main cause of pussy blowing is due to the loosening of the vaginal wall, which is also due to the pressure of the first dewlap on the pelvic floor during vaginal delivery, which loosens the pelvic floor muscles and causes the loosening of the vaginal wall. In this case, besides doing anal contraction exercises in daily life, you should also go to the hospital for pelvic floor rehabilitation treatment. In addition, most of the women with pussy blowing are thin and weak, so it is recommended to strengthen nutrition and give weight gain.
