For some reason, I can't access that article. So, this response is in reference to the subject and what's been said in the comments.

Why does porn usage have to black and white? I argue it doesn't.

Porn is a tool.

There are both healthy and unhealthy ways of utilizing porn. Porn is a great supplement to but not a replacement for sexual expression. Of course, like with anything, porn usage can be a slippery slope.

While I do think having access to porn in our pockets can be detrimental to one's mental health, that's usually relegated to those with fewer scruples. And maybe they shouldn't be reproducing anyway.

For those that do have the wherewithal, porn can be used as a way to express and discover one's sexuality. This is in addition to sex with a real woman/man, as well as in addition to using imagination to get off.

As a married woman, porn has been one if the ways my husband and I have been able to share fantasies, and get to know each other better ("a picture's worth a thousand words"). We don't always use porn, but it is quite handy on occasion, and reduces the burden of being The Only Object of Sexual Desire for Decades on End (no, I don't think sex is just about the physical act, except when it is).

I'd argue people whom are jealous and can't handle their partner's porn usage--assuming said usage is healthy--have some demons to exorcise. (Again, speaking from experience and having dealt with such issues and demons in the past.)

Anyway, those are my two SATs.
