The reason for the sensitivity of the coronary groove is mostly due to the excessive dorsal nerve passage of the penis, high excitability of the central nervous system, etc. The solutions for different reasons are also different, which can be given to the general treatment, medication, surgical treatment and other measures. 1. excessive dorsal nerve passage of the penis: it is a congenital factor, mainly due to the excessive branching of the dorsal nerve of the penis, which causes the nerve threshold to be too low, resulting in the sensitivity of the coronary groove. You can use local anesthetic drugs such as lidocaine gel topically, and if necessary, you can also give the dorsal penile nerve block. 2.. Central nervous system excitability is too high: for example, often contact with obscene videos and frequent masturbation, central nervous system excitability increases, so the coronary groove will be more sensitive, need to improve the bad habits, sexual life can be applied to inhibit the nerve transmission of drugs such as dapoxetine. The specific situation is recommended to go to the hospital, improve the auxiliary examination, clear cause, by the professional physician to give treatment, drugs need to be used under the guidance of a professional physician.
