Like alcholics and drug users, those addicted to porn rarely realize the harm it's causing them until such harm becomes substantial.
I am definitely not "addicted to porn" (for the most part, it tends to be kinda repulsive)--or to alchohol, drugs, or anything else--never have been--not coffee, tobacco, gambling, anything. Never been a smoker. I have the opposite of an addictive personality. It's a matter of luck, not virtue.
On the other hand, I am an adult, and if I choose to watch skin-flicks--or drink coffee or alcohol, or smoke cigarettes, or whatever--it's nobody's business but my own. And as to whether or not it is harmful to me--I'm the best judge of that.
Some don't agree. They think that Big Brother or somebody should do an intervention in my behalf--to save me from my inadequacies.
Somehow--I know it's a miracle--I've managed to get through life very successfully making such judgments for myself--and taking full and complete responsibility for the decisions I make. I think I'll continue to rely on that strategy. It seems to be working.
