It turns out that the belly button is connected to the fibers that lead to the spinal cord at that level It also transmits information from the bladder and urethra to your brain.That is why when you touch your belly button, you are stimulating these same areas.

By digging into the navel in some way you're cheating on your brain to think it's receiving signals from other places, imitating the sense of need of urinating or tingling in the groin.

Deep, behind the navel, everything is covered by the parietal peritoneum, a very sensitive structure and whose sensory nerve fibers go to the spinal cord and whose nerves they send the sensation about the bladder and the urethra to the brain. However, in order for this "false information" to be transmitted, you have to touch the "end of the navel", because only slightly inserting the finger in the navel does not It will produce the same sensation.
