Denial consists of surrendering control of your orgasm to another
person, often a domme or dom. You may find that your orgasm is denied,
or just delayed, until a time and place of the dommes's choice. Often
the orgasm must be earned, by some act of kindness or attention to the
domme, or it is denied for a set period of time. For example, "Sorry
dear, you've already had your cummy for January." Some practitioners
use random methods of determining when release is allowed. These
include cards or dice.
Some practice self denial, wherein they don't permit themselves orgasm for a period of time, or based on random methods.
Denial is related to teasing, orgasm control, and chastity.
