The glans feels too sensitive then the possible reasons are: 1, there is a prepuce too long or circumcision, prepuce too long, circumcision can completely wrap the glans, so that the glans is difficult to contact with the outside world, in the long run the glans surface sensitivity is relatively high. The sensitivity of the glans can be gradually reduced due to long-term external friction and stimulation. 2. The threshold of the sensory nerve innervating the glans is too low, which can cause local sensory abnormalities, manifesting as sensory hypersensitivity, often manifesting as a lowered threshold when glans nerve sensory thresholds are measured. This condition can lead to primary premature ejaculation, which requires dorsal nerve block surgery to cut off some of the nerves that innervate glans sensation, thus achieving the effect of reducing glans sensitivity and prolonging sexual life.
