Since most sexual abuse begins well before puberty, preventive education, if it is to have any effect at all, should begin early in grade school. Ideally, information on sexual abuse should be integrated into a general curriculum of sex education. In those communities where the experiment has been tried, it has been shown conclusively that children can learn what they most need to know about sexual abuse, without becoming unduly frightened or developing generally negative sexual attitudes. In Minneapolis, Minnesota, for example, the Hennepin County Attorney's office developed an education program on sexual assault for elementary school children. The program was presented to all age groups in four different schools, some eight hundred children in all. The presentation opened with a performance by a children’s theater group, illustrating thedifference between affectionate touching, and exploitative touching. The children’s responses to the skits indicated that they understood the distinction very well indeed. Following the presentation, about one child in six disclosed a sexual experience with an adult, ranging from an encounter with an exhibitionist to involvement in incest. Most of the children,both boys and girls, had not told anyone prior to the classroom discussion. In addition to basic information on sexual relations and sexual assault, children need to know that they have the right to their own bodily integity.
