Clamped leg syndrome refers to the behavior of women, especially young girls, who cause sexual pleasure by clamping their legs and repeatedly rubbing and pressing on the perineum, which is essentially a form of masturbation. Masturbation includes not only masturbation, but also leg-pinching syndrome. There is no need to be overly concerned about leg-pinching syndrome, which generally does not have terrible consequences. Sometimes it can affect studies and even increase specific diseases such as vulvovaginitis. It is important to give proper psychological counseling to pinch-leg syndrome, and once it is detected in time, to divert attention by giving toys or other means. Sometimes a gynecological examination is needed to exclude specific conditions such as vulvovaginitis or parasitic infections.
