The record of the pervert Nero is available online to get an idea of the world within which Paul is writing:
"XXVII. Little by little, however, as his vices grew stronger, he dropped jesting and secrecy and with no attempt at disguise openly broke out into worse crime. He prolonged his revels from midday to midnight, often livening himself by a warm plunge, or, if it were summer, into water cooled with snow. Sometimes too he closed the inlets and banqueted in public in the great tank, in the Campus Martius, or in the Circus Maximus, waited on by harlots and dancing girls from all over the city. Whenever he drifted down the Tiber to Ostia, or sailed about the Gulf of Baiae, booths were set up at intervals along the banks and shores, fitted out for debauchery, while bartering matrons played the part of innkeepers and from every hand solicited him to come ashore. He also levied dinners on his friends, one of whom spent four million sesterces for a banquet at which turbans were distributed, and another a considerably larger sum for a rose dinner.
XXVIII. Besides abusing freeborn boys and seducing married women, he debauched the vestal virgin Rubria. The freedwoman Acte he all but made his lawful wife, after bribing some ex-consuls to perjure themselves by swearing that she was of royal birth. He castrated the boy Sporus and actually tried to make a woman of him; and he married him with all the usual ceremonies, including a dowry and a bridal veil, took him to his house attended by a great throng, and treated him as his wife. And the witty jest that someone made is still current, that it would have been well for the world if Nero s father Domitius had had that kind of wife. This Sporus, decked out with the finery of the empresses and riding in a litter, he took with him to the assizes and marts of Greece, and later at Rome through the Street of the Images, fondly kissing him from time to time. That he even desired illicit relations with his own mother, and was kept from it by her enemiess who feared that such a relationship might give the reckless and insolent woman too great infiuence, was notorious, especially after he added to his concubines a courtesan who was said to look very like Agripinina. Even before that, so they say, whenever he rode in a litter with his mother, he had incestuous relations with her, which were betrayed by the stains on his clothing.
XXIX. He so prostituted his own chastity that after defiling almost every part of his body, he at last devised a kind of game, in which, covered with the skin of some wild animal, he was let loose from a cage and attacked the private parts of men and women, who were bound to stakes, and when he had sated his mad lust, was dispatched by his freed man Doryphorus; for he was even married to this man in the same way that he himself had married Sporus, going so far as to imitate the cries and lamentations of a maiden being deflowered. I have heard from some men that it was his unshaken conviction that no man was chaste or pure in any partof his body, but that most of them concealed their vices and cleverly drew a veil over them; and that therefore he pardoned all other faults in those who confessed to him their lewdness."
