Reducing glans sensitivity can be done by circumcision, topical application of compound lidocaine cream, etc. Most of the glans sensitivity is caused by glansitis of the foreskin, mostly in patients with long foreskin or circumcision. Since the glans cannot be exposed for a long time, if the hygiene conditions are not good and there is a lot of foreskin, the inflammation of the foreskin will easily recur, so the sensitivity of the glans will increase. For this type of patients, circumcision can be used to reduce the sensitivity of the glans in some patients, but of course, it is not 100% effective. In addition, the sensitivity of the glans can also be reduced by applying a local anesthetic such as compound lidocaine cream around the anterior glans and penis during intercourse. You can also try rinsing the glans and penis with alternating hot and cold water in the shower, which can sometimes be partially effective.
