The sensitivity of the glans after circumcision is considered to be caused by the skin not forming a stratum corneum, frequent masturbation, circumcision and glansitis. 1. The skin does not form a stratum corneum: Because the glans is wrapped in the foreskin without forming a sufficient stratum corneum, the glans is sensitive and fragile because the stratum corneum is relatively thin after the circumcision. 2. Frequent masturbation: the sensitivity of the glans is relatively high due to frequent masturbation, which will gradually return to normal after quitting masturbation. 3. circumcision: when the foreskin is too long, it is easy to form a circumcision inflammation, if the current circumcision inflammation has not completely subsided, temporary sensitivity is relatively high. After circumcision glans sensitivity, must pay attention to local care, if the symptoms continue to be unable to relieve, need to go to the hospital in a timely manner, to identify the cause of targeted treatment.
