		defense.  
		    
		(1) In any prosecution under ORS 163.355 to 
		163.445 in which the criminality of conduct depends on a child’s being 
		under the age of 16, it is no defense that the defendant did not know 
		the child’s age or that the defendant reasonably believed the child to 
		be older than the age of 16. 
		     
		(2) When criminality depends on the child’s being under a specified age 
		other than 16, it is an affirmative defense for the defendant to prove

		specified age at the time of the alleged offense. 
		     
		(3) In any prosecution under ORS 163.355 to 163.445 in which the 
		victim’s lack of consent is based solely upon the incapacity of the 
		victim to consent because the victim is mentally incapacitated, 
		physically helpless or incapable of appraising the nature of the 
		victim’s conduct, it is an affirmative defense for the defendant to 
		prove that at the time of the alleged offense the defendant did not know 
		of the facts or conditions responsible for the victim’s incapacity to 
		consent. 
		     
		(4) In any prosecution under ORS 163.415 or 163.425 in which the 
		victim’s lack of consent is not based on the incapacity of the victim to

		the defendant to prove that, at the time of the alleged offense, the 
		defendant reasonably believed that the victim consented to the sexual 
		contact, sexual intercourse or oral or anal intercourse. [1971 c.743

		(2) In any prosecution under ORS 163.408, when the object used to commit
