Giacomo Casanova's love life is legendary. He had 122 lovers, according to his own count, but if he actually loved them all, well, that's another story. And they fall in love; they've never felt anything like it before, and they can't fathom ever feeling it again. This is how every romance begins for Casanova--or at least that's what he told himself so that he could continue his affair with "honesty."
In reality, he was simply using them up so that he could go play cards with his friends. But now that he was alone, what would become of him? He didn't know. He hadn't thought that far ahead. All he knew was that he couldn't live without her next to him. So, one night when the woman who had been his favorite lover since Venice came by his house looking for more adventure, he showed her where she could find a way into his bedroom through a window on the ground floor. Then he went back upstairs to sleep next to a different woman each night.
This routine continued for several months until one day when Casanova was playing cards with some of his friends from the Academy of Sciences. They were sitting around a large table with piles of money in front of them when the door opened and in walked the woman he had been sleeping with. Her name was Giacomina and she was there with her son who must have been about three years old.

Casanova is a name that has been associated with romance, seduction, and sexual prowess for hundreds of years. The term "casanova" comes from the Italian word for "wanton," which describes someone who lives by their instincts and is not constrained by social norms. It was originally used to describe a man's own personal valet, but over time the role has evolved into that of a suitor.
In modern culture, the term "Casanova" is almost always used in a derogatory sense. To call someone a Casanova is to accuse them of being a seducer - which is exactly what they're being accused of! The word is often used to insult men who have a history of dating several women at once.
So, if a woman calls you Casanova, she means that you have a colorful past and that you know how to use your charms to get what you want. You don't need to be worried about it, though; as long as you don't do anything wrong, there's no reason why you should be called names like that.

Casanova was a name given to many men who were famous for their skill at seduction. The term was first used in print in 1725 when it was applied to the Italian artist and gambler Giacomo Casanova. However, it did not become popular until much later when it was adopted by other notable seducers including Charles Boyer, Paul Newman, and Sylvester Stallone.
People often refer to "the Casanovas of history" to describe men who have been equally renowned for their sexual prowess. While most historians consider Casanova to be a fictional character created by Pierre Choderlos de Laclos, others believe him to be based on a real person known as the "French Rocambole".
In addition to being admired for his skills as a lover, Casanova has also been criticized for his apparent lack of moral values. He is said to have conducted himself toward most of his female partners with strict ethical standards existing only in theory because he always ended up cheating on all of them.
