Excellent point.
I'm no expert--but it seems to me, how do people in the military, esp. those serving in war zones, have time to be "addicted" to porn? What is the line between looking at porn sites during down time, and "addiction"?
I can assure you that those serving in combat and combat support units operating in the field do not have the time nor the access to see a lot of porn if at all. They sure have no privacy. Personnel in rear echelon support units and headquarters units have more access but, where I am, they don't have the time to do much more than work, eat, and sleep 24X7.
