Cunnilingus is a vaginal sound that occurs when women have intercourse, especially after intercourse, the vagina will continue to have a sound like exhaust. This happens mostly in women after delivery or women who have a more frequent sex life. The main reasons for this are: First, if the woman has a normal delivery, the fetus will pass through the vagina during delivery and cause damage to the vaginal muscles and ligaments, causing them to relax, and when having intercourse, the air will easily enter the vagina, and when the vagina is exhausted, there will be a continuous fart-like sound. Some women, due to frequent sexual intercourse, also tend to cause relaxation of vaginal muscles and pussy blowing during intercourse. Some women have kidney deficiency, so when they have intercourse, they tend to have pussy blowing. To improve this symptom, you need to strengthen the pelvic floor muscle exercise.
