Because the roles of men and women who practice Devotional Sex are so different from normal, each role has been given a special name. A woman who practices Devotional Sex is a Princess, and a man who practices Devotional Sex is a Knight.

The reasons for choosing these names are given in Chapter 1 here.

A couple who enjoy Devotional Sex together do not need to use the term `Princess´ - they can use whatever name they wish. Other possibilities are listed here.

A Knight can use the word `Princess´ to acknowledge all his Princess's commands and requests. As well as just acknowledging (eg "Yes Princess") he can use it to show that he is looking forward to obeying (eg "Thank-you Princess" or "With pleasure Princess").

The definition of Devotional Sex lists the five things a woman must do in order to practice Devotional Sex and be a Princess.

The (optional) public symbol of being a Princess is a special ring.
