List of sexually active popes
This is a list of sexually active popes, Catholic priests who were sexually active before becoming pope, and popes who were legally married. Some candidates were sexually active before their election as pope, and it has sometimes been claimed that other popes were sexually active during their papacies. Such relationships were undertaken outside the bond of matrimony and broke the vow of chastity.
There are various classifications for those who were sexually active at some time during their lives. Periods in parentheses refer to the years of their papacies.
For many years of the Church's history, celibacy was considered optional. Based on the customs of the times, it is assumed by many that most of the Apostles, such as Peter, were married and had families. It is clear from the New Testament (Mk 1:29–31; Mt 8:14–15; Lk 4:38–39; 1 Tim 3:2, 12; Tit 1:6) that at least Peter had been married, and that bishops, presbyters and deacons of the Early Church were often married as well. It is also clear from epigraphy, the testimony of the Church Fathers, synodal legislation, papal decretals and other sources[not specific enough to verify] that in the following centuries a married clergy, in greater or lesser numbers, was a normal feature of the life of the Church. Celibacy was not required for those ordained, but still was a discipline practised in the early Church, particularly by those in the monastic life.
Although various local Church councils had demanded celibacy of the clergy in a particular area, it was not until the Second Lateran Council (1139) that whole of the Latin (Western) Rite of the Catholic Church decided to accept people for ordination only after they had taken a promise of celibacy. 
Popes who were married
- Saint Peter (Simon Peter), whose mother-in-law is mentioned in the Gospel verses Matthew 8:14–15, Luke 4:38, Mark 1:29–31. Clement of Alexandria notes that "Peter and Philip begat children" and writes: "When the blessed Peter saw his own wife led out to die, he rejoiced because of her summons and her return home, and called to her very encouragingly and comfortingly, addressing her by name, and saying, 'Remember the Lord.' Such was the marriage of the blessed, and their perfect disposition toward those dearest to them." In some legends dating from at least the 6th century, Peter's daughter is Saint Petronilla.
- Pope St. Hormisdas (514–523) was married and widowed before he took Holy Orders. He was the father of Pope St. Silverius.
- Pope Adrian II (867–872) was married before he took Holy Orders, to a woman called Stephania, and had a daughter. His wife and daughter were still living when he was elected Pope and resided with him in the Lateran Palace. They were murdered by Eleutherius, brother of Anastasius Bibliothecarius, the Church's chief librarian.
- Pope John XVII (1003) was married before his election as Pope and had three sons, who all became priests.
- Pope Clement IV (1265–1268) was married, before taking Holy Orders, and had two daughters, who both entered a convent.
Popes sexually active before receiving Holy Orders
- Pope Pius II (1458–1464) had at least two illegitimate children, one in Strasbourg and one in Scotland, both born before he entered the clergy. Pius delayed becoming a cleric because of the requirement of chastity.
- Pope Innocent VIII (1484–1492) had two illegitimate children during his youth, both born before he entered the clergy. His nepotism towards these has been described as "lavish as it was shameless."  He married off his elder son Franceschetto Cybo to the daughter of Lorenzo de' Medici, who in return obtained the cardinal's hat for his 13-year-old son Giovanni. Later Pope Leo X. Savonarola chastised him for his worldly ambitions.
- Pope Clement VII (1523–1534) had one illegitimate son before he took holy orders, identified as Alessandro de' Medici, Duke of Florence.
Popes sexually active after receiving Holy Orders
- Pope Julius II (1503–1513) had three illegitimate daughters, one of whom was Felice della Rovere (born in 1483, twenty years before his election as pope, but twelve years after his enthronement as Bishop of Lausanne). The schismatic Conciliabulum of Pisa, which sought to depose him in 1511, accused him of being a "sodomite covered with shameful ulcers." 
- Pope Paul III (1534–1549) who, according to some sources, held off ordination in order to continue his promiscuous lifestyle, fathering four illegitimate children (three sons and one daughter) by his mistress Silvia Ruffini after his appointment as Cadinal-Deacon of Santi Cosimo and Damiano. He broke his relations with her ca. 1513. There is no evidence of sexual activity during his papacy. He made his illegitimate son Pier Luigi Farnese the first Duke of Parma.
- Pope Gregory XIII (1572–1585) received the ecclesiastical tonsure in Bologna in June 1539, but subsequently had an affair with Maddalena Fulchini which resulted in the birth of a son, Giacomo Boncompagni, in 1548. Giacomo remained illegitimate but his father later appointed him Gonfalonier of the Church, governor of the Castel Sant'Angelo, as well as governor of Fermo.
- Pope Leo XII (1823–1829), as a young prelate was suspected of having had a liaison with the wife of the soldier of Swiss Guard and as nuncio in Germany allegedly fathered three illegitimate children.
Popes accused of being sexually active during pontificate
- Pope Sergius III (904–911) was accused by his opponents of being the illegitimate father of Pope John XI by Marozia. These accusations are found in Liutprand of Cremona's Antapodosis, as well as the Liber Pontificalis. The accusations are disputed by another early source, the annalist Flodoard (c. 894–966): John XI was brother of Alberic II, the latter being the offspring of Marozia and her husband Alberic I, so John too may have been the son of Marozia and Alberic I. Bertrand Fauvarque emphasizes that the contemporary sources backing up this parenthood are dubious, Liutprand being "prone to exaggeration" while other mentions of this fatherhood appear in satires written by supporters of late Pope Formosus.
- Pope John X (914–928) had romantic affairs with both Theodora and her daughter Marozia, according to Liutprand of Cremona in his Antapodosis.(See also Saeculum obscurum)
- Pope John XII (955–963) was accused by his adversaries of adultery and incest. The monk Benedict of Soracte noted in his volume XXXVII that he "liked to have a collection of women". According to Liutprand of Cremona in his Antapodosis, "they testified about his adultery, which they did not see with their own eyes, but nonetheless knew with certainty: he had fornicated with the widow of Rainier, with Stephana his father's concubine, with the widow Anna, and with his own niece, and he made the sacred palace into a whorehouse." According to E. R. Chamberlin, John XII was "a Christian Caligula whose crimes were rendered particularly horrific by the office he held". Some sources report that he was rumoured to have died 8 days after being stricken by paralysis while in the act of adultery, others that he was killed by the jealous husband while in the act of committing adultery. (See also Saeculum obscurum)
- Pope Benedict IX (1032– became pope in 1044, again in 1045 and finally 1047–1048). He was accused by Bishop Benno of Piacenza of "many vile adulteries." Pope Victor III referred in his third book of Dialogues to "his rapes... and other unspeakable acts." His life prompted Saint Peter Damian to write an extended treatise against illicit sex in general, and homosexuality in particular. In his Liber Gomorrhianus, Damian accused Benedict IX of routine sodomy and bestiality and sponsoring orgies. In May 1045, Benedict IX resigned his office to pursue marriage.
- Pope Paul II (1464–1471) is popularly thought to have died due to indigestion arising from eating melon in excess, though a rumour was spread by his detractors that he died while engaging in sodomy.
- Pope Sixtus IV (1471–1484). According to the published chronicle of the Italian historian Stefano Infessura, "Diary of the City of Rome", Sixtus was a "lover of boys and sodomites" - awarding benefices and bishoprics in return for sexual favours, and nominating a number of young men as cardinals; some of whom were celebrated for their good looks. However, Infessura had partisan allegiances to the Colonna and so is not considered to be always reliable or impartial.
- Pope Alexander VI (1492–1503) had a long affair with Vannozza dei Cattanei while still a priest, but before he became pope; and by her had his illegitimate children Cesare Borgia, Giovanni Borgia, Gioffre Borgia, and Lucrezia. A later mistress, Giulia Farnese, was the sister of Alessandro Farnese, and she gave birth to a daughter (Laura) while Alexander was in his 60s and reigning as pope. Alexander fathered at least seven, and possibly as many as ten illegitimate children, and did much to promote his family's interests - using his offspring to build alliances with a number of important dynasties. He appointed Giovanni Borgia as Captain General of the Church, and made Cesare a Cardinal of the Church - also creating independent duchies for each of them out of papal lands.
- Pope Leo X (1513–1521) was accused, after his death, of homosexuality (Francesco Guicciardini and Paolo Giovio). It has been suggested he may have had ulterior motives in offering preferment to Marcantonio Flaminio.
- Pope Julius III (1550–1555) was alleged to have had a long affair with Innocenzo Ciocchi del Monte. The Venetian ambassador at that time reported that Innocenzo shared the pope's bed.
