one survey of 16- to 20-year-olds found nearly one out of four young men and one out of 10 young women admitting they tried to kick the habit but could not.
Does "breaking the habit" mean not spending hours upon hours on porn sites, or does it mean never, ever looking at a naked chick again? The author doesn't elaborate (and I understand that the author doesn't have endless column space) but without more, there just isn't much upon which to assess the extent of the problem, if any.
Obviously it means viewing and using for sexual gratification, because that’s what people do with porn, on a regular basis, and even when wanting to stop, having a hard time not doing it.
It is unclear whether “looking at a naked chick” means having a personal relationship with a real woman, or using porn but not habitually.
If you reduce it to absolutes, you don't need any more. Anything is enough for whatever you need it to be.
