No, there is no Church prohibition against writing romance novels, particularly since you are apparently writing them for your own pleasure and not necessarily for publication. But, should you be working toward publication, given current standards in the genre that predominantly demand “sexy” romances, you may wish to take an interest in informing yourself of the Church’s teaching on morality, particularly the virtues of modesty and chastity, and sexuality, perhaps with an emphasis on John Paul II’s Theology of the Body. As a Catholic author, the privilege of publication should call you to the responsibility of writing romances that both uplift the human spirit and uphold the value of traditional marriage.
