Probabilistically your question makes sense. It doesn't make much sense if I think about my personal experience. I don't think my ethics are determined by the law and I don't give much thought to it when thinking about right and wrong. Then again, I know myself imperfectly. My mom was generally obeying the law and my dad was breaking it. I learned from both of them. In Finland, the age of consent is 16. I disagree with it, but don't really care to elaborate how. I find it really hard to be judgemental about sex.

In Italy the age of consent is 14, it can go down to 13 if the partner is at max 15 years old, but it raises to 16 if the partner is a temporary or permanent authoritative figure, like a coach or a teacher. 18 is the limit at which it is allowed to publicly show or sell pictures/movies about that person naked or performing sexual acts. I frankly feel that this is one of the very few cases where Italian laws get the facts right: thirteens would still (try to) have sex wether or not it was allowed. I remember that I believed too that the age of consent was 18, and felt fine with it, so it was a little shock to discover that the limit was much lower. I later however got various data about how sexual expression/desire/maturity starts around that age (mine too, FWIW), so I reconsidered that this was indeed a case of a law just making common sense: you don't throw in jail a teenager just because of his/her natural impulses.
