How many wear dentures (false teeth) with a "plastic plate" at the
top of your mouth?
Try removing that "plastic plate" and eat some food.
The food will taste different as your nerves on the upper mouth get
exposed for the first time again, the texture, the flavor,
temperature of the food as it rolls in your mouth, and is in DIRECT
CONTACT with those nerves.
Sex without condoms will give the same results.
Beware, don't get burn...
