Seeking expert counseling is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help.
Monitoring your son, when he is such a decent young man, is a betrayal, and if he ever finds out, he will feel (rightly so) that you do not trust him, and he will back away from you and shut you out in little ways.
I understand what you mean..... but I think the issue is more complicated with cell phones and computers.... I am not so worried about him, but the persons/images etc. that he might inadvertently be exposed too.... So your answer is OK...but I think somewhat simplistic.....
All children who are growing up experiment and try to take a look at the bigger world out there and are not perfect..
Truth is simple.
If you cross the line and breach his trust it will be hard to ever win it back.
If he finds you out, what lesson will you have taught him?
That makes more sense to me.... I think the hardest thing...is not monitoring and then something happens and I think I could have prevented it...but I guess this is my problem not his.....
You are overly worried. You might see something that is harmless and then over-react, and will have a break in trust that you do not want to have.
You are so lucky to have a good young man.
You are very welcome.
