13 year old eats with his fingers

As long as his hands and nails are clean it shouldn't be a problem.

When i was younger I often ate with my fingers, my family was strange.  I was in my twenties when people at college became concerned about my eating habits.  I held a knife and fork properly and ate with my fingers at the same time.  In fact the metal cutlery was unused while I ate. 

Thanks for your reply. Did you do this because it was a sensory issue? Poor fine motor skills or not like the sound, feel or taste of the metal cutlery? 
or the need to be in control if your food? 

My parents were borderline mentally ill and neglectful.  As a child I was never taught to use cutlery, eating fish & chips was always with my fingers and I loved chicken which I also tore apart with my fingers.  I only used spoons for soup.
