This is from Gregg Frazer on Morris' "kinky" behavior:
There is another factor separating Morris from Christianity, or at least highly inconsistent with Christian faith – Morris’s immoral conduct. As to reputation, when he was nominated to be minister to France, Roger Sherman said of Morris that “with regard to moral character I consider him an irreligious and profane man.” James Monroe said: “Upon the grounds of character he was twice refused as a member of the Treasury Board.” Though he publicly defended his appointment of Morris, George Washington wrote to Morris about his “imprudence of conversation and conduct” and asked him to display “more caution and prudence” and “more circumspection.” A few years later, Monroe referred to Morris as “a man without morality.” Of course, this could have simply been a matter of political partisanship or personality conflict, but, in Morris’s case, the reputation was well-earned. Morris once threatened to kill a man if he spoke disrespectfully of him, and he frequently got “very drunk” while in France. His most conspicuous moral problems concerned women, however.
Morris had numerous illicit affairs with married and unmarried women and, by his own admission, was constantly trying to initate new ones. One of his earliest dalliances may have cost him one of his legs. One account of the loss of the leg, which is reported as fact by most biographers, is that it happened as a result of a cart accident. There is a good chance that this was merely a cover story, however. There is reason to believe that Morris lost his leg jumping from a window to escape a jealous husband. John Jay joked about it in a letter of consolation to Morris and Lord Palmerston testified that Morris told him the whole story at breakfast a decade later. There is also circumstantial evidence surrounding the woman involved which lends credence. Morris denied the story in a letter to Jay, but not very convincingly. If true, the unfortunate event did not dissuade Morris from similar activity in the future. In fact, he used the curiosity afforded by his one-legged status to attract and seduce other women.
Morris’s diary entries during his time in France are filled with sexual escapades. He had an ongoing affair with Madame de Flahaut for more than three years. She and Morris were eventually so “wanton and flagrant” that they engaged in intercourse “in the passage … at the harpsichord … downstairs … the doors are all open,” and in a coach with the coachman staring straight ahead. They became so shameless that they engaged in intercourse inside a convent and even tried to conceive a child while she denied her husband conjugal rights. Morris’s diary contains at least eighteen references to their sexual liaisons, but Morris claimed that they had made love “several hundred” times. In addition to Madame de Flahaut, Morris reported having affairs with Madame Simon, an unnamed “damsel,” Madame de Lita, Madame de Crayen, Miss Matthiesen and her “young sister,” Miss Gehrt, and Mrs. Perez Morton. According to the diary entries, he tried to seduce – or thought of doing so – Madame de Flahaut’s niece, Lady Webster, the “daughter of a Frenchman,” Madame Foucault, the daughter of his landlord, Madame de Nadaillac, Madame de Fontana, and even Dolley Madison! Everyone except Jesus sins, but the extent, duration, and brazenness of Morris’s immoral conduct must call into serious question the idea that he was a Christian. Jesus said that a tree is known by its fruit.
