I'm 18 and my boyfriend is sixteen, and we are thinking about becoming sexually active. I know that the age of consent is 18 in Oregon and that it is illegal until he reaches this age. However, I then researched and found the Oregon law 163.345 for cases "in which the victims lack of consent was due solely to incapacity to consent by reason of being less than a specified age, it is a defense that the actor was less than three years older than the victim at the time of the alleged offense." It says it is a defense, but does that completely protect me? Can I still get arrested, but not be prosecuted? Because it's technically still illegal, right? Is there any possible lasting negative ramifications or does that defense fully protect me?
