Multiple studies exist showing that men and women have very very different views on pornography and in particular women's views on it are significantly more negative than men's views. Furthermore people's views on pornography change as they get older with older people having an even more negative view about it than younger people. This isn't like a fringe difference either, consumption of porn by women is less than 20% that of men. There's nothing sexist about pointing out that women can and often do have very different views on a subject than men, and no reason to think that women having a negative view of pornography somehow makes them inferior in anyway.
