The picture on the right shows the different zones on the glans. There is an extra zone behind the glans edge.
The different spots are usually differently sensitive.
The feeling of a glans drives more to the desire to cum than it can be used to cum. It is possible, but it is much easier to do with a foreskin. The sensation in the glans makes the penis more wild. This reduces on a bare dry head. If a glans is often or always exposed, a thin extra skin layer forms that feels like felt. Then stroking or rubbing can be very pleasant.
The feeling becomes deeper on a covered or wet head. With oil, for example, a glans from a circumcised willy can feel a bit like how it should have been with the foreskin.
The different glans zones can sometimes get “bored” if the same spot is touched too long. Alternating glans spots is the best way to enjoy a glans. When playing with someone else’s glans, be careful not to get too intense.
Suffering from a too sensitive glans is because the feeling that makes the willy wild is simply too intense. It can feel just as unpleasant as getting an electric shock or accidentally eating something you really don’t like. It can also be compared to feeling a shower that is too hot. Since being allowed to get to someone’s willy is something intimate and has to do with confidence, trust can be immediately withdrawn in such cases. So be careful with hypersensitivity.
