Lothario: Meaning and Usage
A “lothario” is a man known for having sexual relationships with many women. In present-day dictionary use it functions as a common noun, typically with a negative or disapproving implication rather than as a neutral label for dating.
Use “lothario” for a man characterized as a habitual seducer or womanizer; it is not a neutral synonym for “boyfriend” or “single man.”

Quick tests
Meaning-and-tone test
Are you deliberately describing a man as a habitual seducer rather than merely describing his relationship status?
If yes: “Lothario” can fit, with attention to tone.
If no: Choose a neutral factual description if that judgment is not intended or supported.
Caveat: Modern dictionaries treat the current sense as a common noun; lowercase is ordinary outside sentence-initial or title-style capitalization.
Examples
The fictional character is portrayed as a lothario.
The sentence uses the common noun for the documented character type.
He is single, so he is a lothario.
Better: He is single.
Being single alone does not establish the word’s documented meaning.
The article called him a “lothario,” attributing the characterization.
Attribution makes the judgmental label explicit.
Further guidance
Capitalization
Modern dictionaries treat the current sense as a common noun, so lowercase is ordinary unless the word begins a sentence or appears in a title style that capitalizes it.
Meaning
The word describes a type of person rather than simply a relationship status.
Tone Boundary
Because the label judges a person’s sexual or romantic behavior, use it carefully in neutral reporting.
