I sometimes chew on my keyboard
That's seems like a bad idea. Why do you chew on your keyboard?
I like the feeling of having something in my mouth when I am on the computer.
It is not good to chew on electronics, you can get shocked or break them. You may damage your teeth if you keep chewing on objects.
I'm a mutant and I have a superhuman strength. You don't need to be scared of me.
I suspect that you are not actually a mutant. Therefore chewing on the keyboard is bad for both you and the keyboard. You need to find a safer substitute to chew on.
