where you can talk to him about it and have him work through it together and figuring out how to regulate himself, or would you rather he have to figure that out on his own after he leaves the house? Because I will tell you this, I had many cousins that didn't have access to pretty much anything. And almost to a boy they dealt with extremely heavy actual sexual addictions once on their own. Sure you don't let them go lord of the flies on you, but creating a space where you can talk, they have to make choices and see the consequences is important.
