My 5 yr old son has been humping his hands and has been caught twice messing around with little girls. He has been humping his hands for about 3 yrs and it recently came to my attention from my son that my ex-husbands ex-girlfriends now 8 had touched my son about 2yrs ago. I had him taken to the child advocacy center and a doc. did "play therepy" with my son and said there were no signs of sexual abuse, this was about 2 yrs ago when he had started humping his hands. A few monthes ago he and another little girl got caught by her babysitter humping eachother. My son told me she wanted to play the butt game. Then yesterday I caught him at the playground on top of a little girl and he said they were touching boobs together and that her and her brother who is 4 and she is 7 were "sexing". I dont know what to do or say, i dont know if I should yell or punish him. His doc said humping is normal, but with him touching others, my concern for his well being is worrying me. How do I handle this? who do I talk to? What should I tell my son and should he be punished? I've explained its innapropriate and should never touch anyones privates. I dont know how to approach this subject, my boyfriend thinks I should be really hard on him, but I dont know what to do, Please Help!!!!!
