My 14 year old ds has aspergers. He is very immature and not able to cope alone for long. I looked through his phone last night and he's been watching porn through a private network. Lots of porn. Then I found a chat on Instagram where he was asking another teen from his school to meet up to have sex. This other teen is proudly bisexual but from the photo and name I have no idea whether it's a boy or girl. Not that it matters either way but the consequences are different.
I'm totally out of my depth and have no idea how to respond to any of this. I've hidden his phone until I get a chance to speak to him later as he is very sneaky and will delete it all if he thinks I've been looking.
How do I deal with this?
