Or, is it mainly to do with seeking out the intense pleasure of the physical experience? Your preschooler will continue to learn important sexual attitudes from you — from how you react to people of the opposite sex to how you feel about nudity. If she can't be persuaded to change course, abandon ship and look away. Then, like at home, you and the teacher need to find some creative ways to distract her or divert her attention.
