Private Humiliation

Performing actions in private that would otherwise cause humiliation.  These acts can be done without another's knowledge, simply for your own enjoyment, or under the guidance of another, such as a Mistress or a Master.

This can entail any action that would humiliate you or cause you discomfort or embarrassment if performed in public.  Common forms include self-induced bondage, feminization (which can be done by either gender depending on the level of feminization), masturbation to forms of pornography that would otherwise provide little or no satisfaction, infantilization, urinating onself, and cumming on oneself.

But, private humiliation like public humiliation is very personal and the actions performed are determined by what causes the individual discomfort or embarrassment.
