Your posts are like a mine field that can explode at any moment. I think that one has to consider the great variety of cultural sexual norms and behaviors across space and time. Some cultures are or have been more permissive than others in certain sexual matters but not in others. Engaging in sex and dealing with the consequences that go along with it is a life altering decision, especially for young ones. In western culture, we have decided to extend childhood by delaying sexual maturation (at least in theory). As you said, technology influences what we see and hear, so we're charting new territory as far as sexual development is concerned.
