In porn, lust always triumphs and women are always inordinately pleased. That's why they call it fantasy. The second paradox of porn is that women are always said to be just about to become major consumers of pornography but never do, somehow. The market has spoken. There is already erotic literature for women, of course, but it is not called pornography, because pornography is, by definition, what appeals to indiscriminate male lust.
Pornography is sex stripped of all but the most desultory demands of narrative.
The female equivalent is the romance novel, most of which are pretty sexual indeed, and just as formulaic. But women want 200 pages of storyline before the climax and a wedding somewhere around the corner afterward. For instance, many women love the fantasy of being taken. That's why they call it fantasy. Moralists such as me may call for a porn crackdown.
