A womanizer is a man who frequently has multiple sexual or romantic relationships with women, often without the intention of committing to any one of them. This behavior is typically marked by deceitfulness or a lack of compassion regarding the feelings of the women involved. Womanizers may lead women to believe they want a serious relationship or are in love when, in reality, they are seeking attention, validation, or sexual encounters with as many women as possible. Key characteristics of a womanizer include:

• Being overly flirtatious and charming with many women.
• Avoiding commitment or clearly defining the relationship.
• Creating emotional highs and lows, resulting in unstable emotional experiences for their partners.
• Often having a history of multiple casual relationships and sometimes blaming past partners for failures.
• Using emotional manipulation and avoiding genuine emotional vulnerability.

The term usually has negative connotations, implying manipulative or self- serving behavior toward women, as opposed to simply being charming or dating several people casually without deceit. Womanizers often prioritize their own desire for attention and validation over the emotional well-being of their partners. This term is distinct from similar words like "philanderer" and "Casanova" in its modern usage and implied negativity, with "womanizer" often highlighting manipulative intent.
