Again, porn does not cause this. This is the fault of the person who is abusing the porn. Absolutely everything in life can be abused and misused
regardless of how healthy it is. Some people can't drink at all because it becomes a problem for them. Same thing with porn. If you can't handle watching porn a healthy amount, then don't. But just because you can't that doesn't mean there is anything inherently wrong or unhealthy about porn.
