My son is 12, is a great kid, but sudenly he became obsessed with sex. He masturbates frequently, sometimes in front of othe people. He told us that he masturbated wearing his sister's clothes (lingerie - bra and panties). He said that sometimes he looked at other boys butt's, and that he even looked at his own mother in a lustful way. He is very candid about his actions, and he ends up telling us everything, but he is feeling very ashamed of his actions and thpughts. He even asked rethorically why he is still living, if he is being so bad as a person. I am very worried, specially because all that happened too suddenly, since a few days ago all he thought was cartoons and videogames.
Could you help me understand and deal with that?
