(c)  Compulsion within the meaning of this section exists only if the force or threat of force would render a person of reasonable firmness incapable of resisting the pressure.
(d)  The defense provided by this section is unavailable if the actor intentionally, knowingly, or recklessly placed himself in a situation in which it was probable that he would be subjected to compulsion.
(e)  It is no defense that a person acted at the command or persuasion of his spouse, unless he acted under compulsion that would establish a defense under this section.
