The term "woman of the town" is often used to describe a woman who is known for her promiscuity and reputation for engaging in casual sexual relationships. While this term can be derogatory, there are other less offensive synonyms that can be used to describe women who engage in non-traditional sexual relationships. Some of these terms include "sex worker," "escort," "high-class courtesan," "mistress," and "paramour." However, it's important to remember that each of these terms has their own connotations and should be used with respect and sensitivity towards those who identify with them.
