There are many reasons for glans and coronal sulcus sensitivity, mainly due to the lower excitation threshold of the dorsal nerve of the penis. Since the excitation threshold of the nerve in the coronal sulcus of the penis is low, the coronal sulcus can be excited under smaller stimulation, causing the coronal sulcus to be more sensitive. There are many reasons for coronal sulcus sensitivity, partly due to congenital factors and partly due to acquired factors. The congenital factor may be related to the richness of the dorsal penile nerve. For such patients, topical lidocaine local anesthesia can be used to reduce the sensitivity of the glans. Acquired factors may be related to the glans and prepuce, the glans is wrapped for a long time causing the coronal groove to be more sensitive and cannot be controlled at the slightest stimulation. For this type of patients, it is recommended that they be circumcised. It may also be related to inflammation of the coronal sulcus, when the patient has inflammation of the coronal sulcus his skin is more tender and part of it will have inflammatory exudation. For this part of the patient, you can treat with topical ointment, the inflammation disappears the glans sensitivity will also be reduced accordingly.
