Excessive sensitivity of glans penis can lead to psychological or physiological diseases such as premature ejaculation. How to reduce the sensitivity of glans penis, the commonly used clinical methods are: 1, circumcision. For patients with too long foreskin or phimosis, the sensitivity is relatively high because the glans penis is wrapped in skin for a long time and rarely stimulated by the outside world. After circumcision, the glans penis is exposed to the outside of the foreskin, which can be stimulated by the outside world and gradually reduce the sensitivity of the glans penis over time. 2. Surgery can be performed to block the dorsal nerve of penis. After the dorsal penile nerve is blocked, the sensitivity of glans penis can be reduced and the sexual intercourse time can be prolonged. However, the distribution of penile dorsal nerve is individual, and some patients have complications such as poor postoperative effect or loss of penile sensation. Unless the patient has a strong will, surgery should be used with caution. 3. Local topical anesthetics, such as commonly used delay cream or tetracaine cream, can be applied to the surface of the glans penis, which can reduce the sensitivity of the glans penis. However, the onset time is short, so it should be used temporarily, and the sensitivity of glans penis cannot be reduced for a long time.
