In general, girls usually refer to the lower part of the perineum, and the lower part of the girl’s bump is considered to be the normal mons pubis area, which is relatively high. For girls with a thin body type, the pubic arch forms a certain angle in the mons pubis, and the different angles will lead to different degrees of mons pubis protrusion, and the fat layer in this area is thicker than the fat layer in other parts of the perineum, so it will appear more protruding. If there is a local bulge in the labia majora on both sides, it is possible to have a vestibular gland cyst. It is recommended to go to the hospital for examination and take medication or surgery under the guidance of a doctor. It is recommended to pay attention to perineal hygiene, especially during menstruation, and not to use gynecological lotions excessively to clean the vagina.
