First of all, leg clenching syndrome is a form of masturbation. If you suffer from leg clenching syndrome for a long time, it can be very harmful to women, for example, it can lead to psychological problems such as low self-esteem. In addition, the process of leg clenching can be unhygienic, sometimes resulting in bacterial infections that can cause urethritis or vaginitis. Of course, long-term leg clenching syndrome can lead to vaginal laxity, which may have a negative impact on the future life of the couple.
