What man did Napoleon kiss?

There is no credible historical record of Napoleon Bonaparte kissing a man in a romantic context, and claims about such incidents are generally myths or misinterpretations of 19th century customs. Napoleon was known to be affectionate with his close family and loyal marshals in ways that reflect European customs of the era rather than romantic relationships. In French and Corsican culture at the time, it was common for men to embrace and kiss on the cheek as a sign of friendship, respect, and fraternity, similar to the modern French la bise greeting. Napoleon was known to embrace his marshals after victories, and he had close platonic friendships with men like Marshal Jean Lannes, General Louis Desaix, and his stepchildren. Some anecdotes mention Napoleon kissing his old school friend or his brother on the forehead or cheek as a greeting, which was standard etiquette. The most famous kissing anecdote involving Napoleon is actually him kissing his wife Josephine and later Marie Louise, not a man. If you are referring to a painting or story, you may be thinking of the tradition of the fraternal kiss or accolade given when knighting someone or awarding the Legion of Honour. There are no verified romantic letters or accounts suggesting Napoleon had a same-sex relationship, and historians generally describe his romantic life as focused on women, particularly Josephine and Marie Louise.
