My 4 year old boy won't stop touching his privates. When I or someone else is talking to him his hands are at his privates. When he is just sitting, working at his table, eating, reading, playing games, he is touching himself. It is very distracting to interact with him and see that he is doing that. I have explained to him about his private parts and that it makes others uncomfortable to see him do that and that private parts are to be kept private. He gets frustrated that people ask him constantly if he has to go potty. I am constantly moving his hands away from there, telling him to move his hands, telling him to do something else with his hands. Today he said he can't stop. What do I do to get him to stop this behavior? I try to distract him and occupy his hands but it is not enough.
