Russel Moore considers the similarities between pornography and romance novels:
Both are based on an illusion. Pornography is based on the illusion of a perfectly willing, always aroused partner without the “work” of relational intimacy. Often romance novels or their film equivalents do the same thing for the emotional needs of women that pornography offers for the erotic urges of men.
And in both cases, what the “market” wants is sameness. Men want the illusion of women who look just like women but are, in terms of sexual response, just like men. Women want the illusion of men who are “real” men, but, in terms of a concept of romance, are just like women. In both artificial eros and artificial romance, there is the love of the self, not the mystery of the other.
