I'm thinking about using lignocaine jelly because I've heard it can help reduce the sensitivity of the glans penis, but I'm wondering how this might affect the process of getting an erection. I'm planning to apply it, but I'm a bit confused about how it all works together. Could you explain how lignocaine might impact erection and whether it's safe to use for this purpose?

Lignocaine jelly works by numbing the area it is applied to, reducing sensitivity. However, an erection is primarily caused by physical and psychological stimulation, leading to increased blood flow to the penis, not just sensitivity. So, even if the glans penis is less sensitive, the erection can still occur due to these other factors.
