My 13 yr old stepson is trying to "humping" all the furniture in his room, the bed rails, the bed, the chairs, the tv, the wall, the curtians, the holes in the curtians, the pillows and most disturbingly trying to hold my cats down to do the same. He is also changing underwear about 14 times a night. Sometimes not even his underwear, other family memebers, he will put shirts on with his legs threw the arm holes and his privates sticking out of the head hole.
I am pretty worried about him. This is not the first time I have found him doing odd things sexually. When he was 10 I caught him trying to have sex with my small dog. He has a speach problem and has failed 2 grades. I have begged his parents to get him tested for mental disorders, social disorders or learning disorders. I don't know what to do or if I am over reacting about this. I just don't think it is normal to do this. And as a disclaimer I would like to add that I only know about this because I set up a motion camera in his room because I could not get his father to beleive he was trying to have sex with my cats. Not the most trustworthy thing for a stepmother to do but I had to know for sure.
