Hi Paige,

That's really interesting, so your literally teaching your body to associate those sensations with a particular part of your body by looking at it as you're touching?
Absolutely. Originally, gland penis would have been external to the body by 1.5-5" the brain learnt that over time by visual reference supported by touching sensations. Brain now has a synapse called gland penis, so when an object hits it, the brain looks at the nerves that respond to the hit and relay that message as a hit to the penis. Your entire body is mapped for that purpose. Left arm, right leg, thumb, little toe etc. Post op things change. The brain hasn't got an eye, it depends on the eyes for visual affirmation. Testes are now gone, nothing to connect to, they atrophy as does the electrical impulses (synapses) to the brain. Gland penis still intact but relocated. Nerve endings still connected, they need to be remapped to an internal location. Thus if you look and say your new parts, the brain has the affirmation to let you know what and where its all happening. Clever brain.

I do find the way the brain and body works so fascinating. I assumed it would realign itself over time just by natural movement/touching and relating those sensations to the existing nearby nerves.
The brain maps the body by information from the optic nerve and sensations derived from sensory touch with the appropriate name given to it. Left thumb, right big toe, right knee, left elbow etc. Nerves on the other hand are very body specific. Hence an amputee looking for prosthesis replacement has to go through training to (a) find the right nerves associated with thumb, little finger, wrist etc and (b) re strengthen the associated atrophied synapse.
So the old saying of use it or lose it, to some degree is true.
Can you move your toes independently of one another? Titch titch. Shame on you. It's because you have never tried, because there has never really been a need to. Well then, look at the dexterity of those artist who paint with their feet. Quite refreshing to see what you can get your body to do, isn't it.
Speak to you as soon I put the milk bottles out and bring the cat in.
