Push them together as hard as you want, and they will resist.
Two like charges always repel each other. And also no two objects can have the same exact properties ( courtesy of the Pauli’s exclusion principle ). This curtails any possibility of two objects coming together.

This goes beyond our intuition because we know it when we have kissed someone. That adrenaline rush and the dopamine surge is just inevitable! You feel it, yet not touch?
