dihahey, small children often discover themselves sexually before they even know what it means. All the child knows is it feels good and often children are curious if other children can experience it too. Children are curious about everything and like to explore, it's just their nature. If you remember this keep in mind that children really don't know what it means like adults do and it really is very common for children to explore more than most realize. When an adult takes advantage of a child, that creates issues because it's sexual abuse and results in some major trust issues and confusion and guilt later on. Unfortunately, most parents fail to explain to children how not to explore with other children and because of children being normal and discovering themselves sexually, and being curious this happens a lot more than people admit.
