Another Roman Emperor who engaged in a public same sex marriage was Elagabalus:

“.....Another emperor who “married” men was Elagabalus, who ascended the throne in A.D. 218 after a substantial bribe was offered by his powerful grandmother(.....)The emperor’s first “husband” was a blond slave named Hierocles. Elagabalus was described as being “delighted to be called the mistress, the wife, the queen of Hierocles.” In addition to playing sado-masochistic games with Hierocles, Elagabalus pretended to be a prostitute out in public, offering himself naked to random pedestrians in the palace or prostituting himself in the brothels and taverns of Rome.
The Augustan History states, “He set aside a room in the palace and there committed his indecencies, always standing nude at the door of the room, as the harlots do, and shaking the curtain which hung from gold rings, while in a soft and melting voiced he solicited passers-by.”....”
I do not care how liberal you may be. How can you not read the behavior of the Roman Emperor Elagabalus, and not see Satanic influence. What if this happened to America in the future? The Lincoln Bedroom could become a brothel.
In dealing with the accounts of Roman emperors you have to take some of it with a bit of skepticism. We can only rely on a very small sampling of very biased contemporary writers. The contemporary histories we have access to were the political propaganda of its time. These writers were not above delving into personal slander. Sometimes their objective was to savage previous emperors in order to show how great the current one is, especially if those past emperors were from rival families. Nero was despised for his affinity for Greek culture over Roman culture. A lot of the tales about him were exaggerated to get across the point of the superiority of the Roman over the Greek.
