I didn't know about the abstract, but I can see what they meant for "thinking like a porn director": titillation. It's a strange metaphor, but I think it was about not dragging on for too long and cleaning showing what's amazing about your product. Still, I'm not sure. I don't see how this is celebration: stretching my military example, I've mentioned military discipline in a blog post once. I don't celebrate and personally repudiate most of their actions, but military discipline is a cultural reference that helped explain my point (the blog is long gone so I can't quote it).

I understand why feminists would hate the porn industry—exploitation of women at a young age, pressure on people to conform to unrealistic expectations, etc. But the feminist argument against porn as a thing, the porn industry notwithstanding, is based on some assumptions—that sexuality is always a tool of exploitation, that male sexuality is abusive, and that sexual attraction without affective relationships is inherently exploitive.

Feminists are right to call out the use of sexuality as a tool for oppression, but to see all sexuality as oppression is absurd.
