13 year old eats with his fingers

Conversely, I dislike eating with my fingers, I prefer to use cutlery as I don't want to touch it.

I love the feel of well balanced knives forks and spoons. They should balance on your middle finger. 

It is sensory but the other way around.

I guess we're all different :-)

I wouldn't eat fish and chips with my fingers.

It's not entirely consistent though as you can't eat an orange any other way, or sandwiches.

These are mostly the reasons for me and my siblings preferring eating food with hands. It’s kind of difficult to use cutlery, and all of us are picky so having touch gives another way to inspect the food (like if a strawberry is too squishy). Then my sister especially hates the sound of metal so we use plastic.

I can also imagine maybe it being sensory seeking? 

There are some cultures where eating food with ones fingers is considered the norm. As Robert124 has said, it shouldn't be a problem if your son's hands and nails are clean.

Although I would never attempt to consume something like soup without the use of appropriate cutlery, I am not averse to eating food with my fingers. Sometimes I find that the weight of cutlery is too heavy and I just haven't got the energy to hold it, or use a knife and fork to cut food into smaller portions.

During the colder months of the year, I find that metal cutlery can sometimes feel so cold that it's like holding blocks of ice. If I'm eating food that requires cutlery, then I will sometimes wear a pair of winter gloves.

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.

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? 

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.
