President Lyndon B Johnson was obsessed with his penis and used it to control those around him. He gave it the nickname "Jumbo." He'd threaten Senators by saying he was gonna sleep with their wives and if he went to the bathroom in the middle of a conversation, he expected the other person to follow him into the bathroom to continue the conversation and would get upset if they tried to just wait outside. Sometimes he would swing around while standing at a urinal and talking to someone, leaving his genitals exposed. He also drove himself around on his ranch and stopped to pee on the side of the road so the Secret Service Agents had to cover him and there was a gust of wind that blew the pee onto one of the agent's legs and Johnson said that it was his "prerogative" to pee on the agent's leg. Journalists once asked him "why continue the war in Vietnam?" and he sent all the women out of the room, took his penis out, flopped it on the table and said, "this is why!" -u/SneezyMcBeezy

Hawaiian kings commonly had “harems” of both male and female lovers. The first European to make a Hawaiian to English dictionary didn’t want to scandalize his Victorian readers so translated the term for the male lovers to something like “intimate friend.” This caused some degree of confusion when missionaries arrived asking to become the intimate friends of the Hawaiian nobility. -u/Groen_Fischer

The Mongols had a rule: 'You're not allowed to kill the leader of a country (or city-state) by piercing their skin.' So they came up with ingenious ways of killing people. There were stories of a potential Khan that boiled a man alive; other stories include pouring molten gold down a man's throat. Though not necessarily NSFW, Genghis Khan gave cities the option of surrendering, or face the option of killing every man, woman, and child in that city. He would literally genocide everyone in that city because the ruler wanted to fight back. And that's how Genghis Khan killed 10% of the world's population at that time; 20-40 million people. -u/TheSaltyPineapple1

James Joyce had a fart fetish. He often wrote about it in letters to his lover. "You had an arse full of farts that night, darling, and I f**ked them out of you, big fat fellows, long windy ones, quick little merry cracks, and a lot of tiny little naughty farties ending in a long gush from your hole. It is wonderful to f**k a farting woman when every f*ck drives one out of her." -u/ghigufa

This later became known as the British Pet Massacre. -u/Asaella

Julius Wagner-Jauregg won the 1927 Nobel prize for medicine by giving people malaria The fever from the malaria would go so high that it could kill off an otherwise untreatable syphilis infection.
