Defining the distiction between "Porn" and healthy sexual imagery is the trick we definatley haven't mastered yet, as a whole. I think there is nothing wrong with porn in a healthy, high self esteemed person who sees it as something to stimulate an already healthy drive and desire. However, IMHO the majority is not in this group and the use of porn can be more harmful to any age without the aforementioned characteristics. Porn can act similiar to a drug, a quick thrill, and push what healthy sexuality is further away from that person. With this view however there is even more reason to maintain free and open communication about such matters as communication is a grand tool for education.
