The opusculum De cΕlibatu sacerdotum is on DjVu pp. 192-5. Pope Pius XII cites it in his 1954 encyclical Sacra Virginitas Β§23 regarding priestly ritual purity.
St. Peter Damian wasn't solely against sodomy. He condemned lesser degrees of lust, too, when he harshly criticized clerics' illicitly-married wives (Opus. 6, " Gratissimus " liber to Abp. Henry of Ravenna, col. 145, DjVu p. 74, transl. from Elliott 1993 p. 103):
I speak to you, O you the clerics' charmers, Devil's choice tidbits, expulsion from paradise, virus of minds, sword of souls, wolfbane to drinkers, poison to companions, material of sinning, occasion of death. You, I say: I mean the female chambers of the ancient enemy, of hoopoes, of screech owls, of night owls, of the she-wolves, of the bloodsuckers, which say: Give, give! without ceasing (Prov. 30.15). And so come, hear me whores, prostitutes, lovers, wallowing pools of greasy hogs, bedrooms of unclean spirits, nymphs, sirens, lamiae, followers of Diana . . . For you are the victims of demons destined to the fall into eternal death.
Elliott also cites De cΕlibatu sacerdotum , Op. 17, col. 379-87 (DjVu pp. 192-195), also called Letter 61.
He's right in calling them those names β΅ they certainly practiced abortion and contraception.
Happy feast of Pope St. Leo IX's successor Pope Hildebrand, Gregory VII (1073-85), who were both staunch opponents of clerical lust, despite the latter coming from a usurious family that produced two anti-popes, Gregory VI (1045-46) and Antipope Anacletus II (1130-1138) (vs. Pope Innocent II, which is strikingly similar to Francis I vs. Benedict XVI)!
Elliott p. 97 (PDF p. 113) n. 10: "His treatise De tempore celebrandi nuptias [cols. 659-668 // DjVu pp. 332-6 ] is one of the few treatises addressing marriage directly that had been written since the time of Augustine. This work attacks the misconception that there can be no marriage without coupling, instead alleging that a couple is truly united by the marriage contract ( dotali fΕdere jungitur )."
