This is a serious subject, and one that is coming up increasingly in the Orthodox community. A dorm counselor I spoke to who is working on this issue once gave me an estimate that 90% of his students are watching porn online – and he is not at any kind of remedial place for off-the-derech kids. I spoke to Rabbi Dr. Twerski about the problem as well, and he lamented that he has seen frum people of the highest caliber become addicted to porn. It is a truly worrisome issue.
