This inflammatory denunciation of male sexuality springs from the sexist assumption men cannot feel sexually aroused without there being some element of ridicule or desire to dominate. Pop-feminists really oppose male pornography because it undermines the sexual power of women. A man who can see naked women any time he finds it convenient is not a man very vulnerable to the coy hint of cleavage beneath a woman's blouse. If he's seen so many naked breasts that a woman who hides hers cannot use partial concealment to arouse his interest and, thereby manipulate him, then she has less power over him. Power, however, is not the reason they give because to admit it would undermine their efforts.
Women have no more inherent seductiveness than men do.
Men obsess about women's sex because generations of women have set themselves up as sellers of scarce female sexuality. With their sexuality and sensuality. Take this away, and they would have to work to attract men with their personality and intelligence. This, as men well know, is a tough arena in which to compete for the attention of another. Easier by far for women to maintain their ability to employ the sexual sell by outlawing pornography for men.
