Also, like any fantasy based pasttime porn has it's own addiction dangers that would not necessarily be considered 'healthy'. Although this of course would not apply to people who are not prone to fantasy addiction in the first place, there is a reason that internet porn is a multi-billion dollar industry.
>Note: Just to clarify, I don't have any issues with the act of making, staring in, or viewing porn itself. I do watch porn. And I know that addiction occurs across all industries and walks of life. It does happen to have a higher occurrences in certain industries though, such as, for example, adult entertainment or telemarketing. I personally do not view porn as either bad or immoral.
