Promiscuity is a term that describes someone who engages in multiple sexual relationships without any commitment or loyalty. A promiscuous man can be referred to as a playboy, womanizer, gigolo, libertine, or lothario. These synonyms carry connotations of a man engaging in sexual activities without any emotional attachment. Other synonyms for promiscuous man include philanderer, Don Juan, or Casanova. All these words suggest that the man is not interested in a serious or committed relationship but is more focused on physical pleasures. However, it's important to note that promiscuity can occur in both sexes and is not limited to men only.
