I don't think that pornography is a great introduction to sexuality for any child and certainly not for one as young as ten years old. A ten year old needs to know that girls are pretty, fun, interesting, great companions and wonderful friends. If a child is curious about sexuality at that age, parents can explain, the old-fashioned way, that men and women are attracted to each other and their bodies are especially designed to show love to each other and make babies and that more information about the details of all this will be delivered when it is appropriate for him to know more. Ten year olds should (in my opinion) be left to enjoy a few more years of childhood. Teenagers do need much more detailed information about sexuality, but this too should be couched in terms of affection, respect, caring and love. The pleasure of sexuality should be balanced with the responsibility of sexuality. Boys and girls need to know that there are people within those interesting bodies and that everyone is emotionally vulnerable. Care needs to be taken not to hurt others. "Sex education" is really "love education" that must include practical information about sexuality and physical health as well as emotional health and healthy relationships. Biologically, men are primed to be visually responsive to women. Pornography is a pleasant pastime for some males. Recent research shows that young brains can quickly become addicted to pornography and quickly need more intense and/or bizarre versions of it in order to maintain a feeling of pleasant arousal. Unfortunately, some of this research (see the book "The Brain that Changes Itself" by Norman Doidge) shows that a young person's brain may be permanently changed by such exposure and be eventually become unable to enjoy normal, ordinary sexual stimulation. A cautionary note.      Sarah Chana
