Books like the ethical slut

The Ethical Slut: A Guide to Infinite Sexual Possibilities is an English non-fiction book by Dossie Easton and Janet Hardy (given as pseudonym Catherine A. Liszt for the book's first edition in 1997).

The authors define the term slut as "a person of any gender who has the courage to lead life according to the radical proposition that sex is nice and pleasure is good for you." The term is reclaimed from its usual use as a pejorative and as a simple label for a promiscuous person. Instead, it is used to signify a person who is accepting of their enjoyment of sex and the pleasure of physical intimacy with others, and chooses to engage and accept these in an ethical and open way—rather than as cheating.
