If the vagina is always exhausted, this phenomenon is clinically known as pussy blowing, and the main reasons are as follows: 1. Women with weaker constitution may not be able to fit the front and back walls of the vagina together, which may cause air to enter the vagina and then be discharged outside the vagina, leading to the phenomenon of pussy blowing; 2. Due to the postpartum pressure on the pelvic floor muscles, the tension of the pelvic floor muscles decreases, causing the front and back walls of the vagina to relax. Air can easily enter, which can also lead to pussy blowing. Clinically, it is recommended for thin women to gain weight to make the pelvic floor muscles plump and fatty, and this phenomenon will improve or disappear completely. In addition, if it is after childbirth, you can do pelvic floor rehabilitation therapy, so that the pelvic floor muscle tone recovery, this situation will also improve.
