I think the critical developmental point here is the teenage brain. In the teenage brain, the frontal lobe, which is responsible for all the decision-making, weighing the pros and cons of risks, that type of thing, is functioning.... Let's just say the amygdalic system—which is where all of the thrill and the dopamine rises and so on happens—is working at a much faster rate in the teenage years than the frontal lobe is. They're both still developing, but the frontal lobe continues to develop all the way through into your mid-twenties, 26, 27, 28, which is something we didn't realize several years ago and one of the reasons you tend to see teenagers taking risks. It's because, for their brain, it's more pleasurable for them to do that than to think through all the actual risks. It's possible that if viewing pornography in any form is giving them that high, that is something that's going to increase over and over and potentially lead into some more risky behaviour on their part.
Does that make sense?
