I'm just curious about this and I don't do this kind of thing at all.(Check out my other threads to see why.) But why is it that (at least in the US) one can look at a pic of an 18 yr old and it's fine but if the pic is of someone who is 17 then it is a crime? I know that 18 is the age that you are legally an adult and everything but why does that also apply to this? How can one year decide whether the person was able to consent or was just being exploited. It makes no sense. It is just one year. It's not like people completely grow up in a one year span. I am just curious about this subject is all.
