You told him not to "Dont trust strangers" so why should he listen to you?
Dont trust strangers. If you want to, talk to a smart uncle, esp one who is an early to middle adult (he may be more comfortable with talking about the issue) perhaps a school counselor if it means that much to you or a family member you like and trust. And also do some more reading.
How many times a day were you actaully getting off (sorry but I don't know how else to ask you) watching porn when you were able to do it at will?
You need to back off watching the porn as much as possible as quickly as possible to reset your pleaseure sensors when it comes to sexual activity. Once this is done you will be back to the point you were when you first started to watch porn. It will be tough but you must od this. It is best to gradually back off.
Let me know what you think about this concept.
