Teens need porn, it's as simple as that. OK, make sure they're not doing sick wrong things but on the other hand don't be intrusive, if I found out my dad had been spying on me back in the day I'd have been pretty narked. If you really have to do anything set up a web tracker. Reading your kids conversations is as bad as listening to their phone calls.
Sorry, had to be said.
Don't laugh at me.... Thank you
