Guys help something is going on with my son. So I(41M) have been having a lot of trouble with my son recently. It started out 3 months ago he would start randomly and loudly moaning during eating, he also often started rubbing and smearing the food on him. Then he also started randomly crying during eating. He also would masturbate and cum during eating and he also started going through my wife's (5F) and mine (63M) drawer and cumming in our underwear. Now this would all be normal after all he's a teenage boy and I did the same thing when I was his age. However what made me really caucious was when he started shitting in his hand and smearing it against him and when he would add the shit into his potato porridge and he would eat the whole thing. So I (68M) went looking around his room and wanted to look in his laptop to maybe find what was causing his strange behavior. I open a file titled as "Porn" and find numerous "Nikocado Avocado Fart Compilation" videos. Unfortunately I hear him coming back so I didn't want to be caught by him so I hide in the locker. Then I watch as he sits down and starts watching one of the videos and starts loudly moaning and masturbating and cumming while he is smearing against his body a yoghurt he brought for eating. I was extremely disgusted by this so I got out of the locker thinking I have to go to the toilet to vomit, however I didn't make it in time to the toilet and vomited all over his locker and room and ran out of his room. Now I am sitting here wondering how can I help my son, guys if any of you have any idea what to do please send help.
