Daddy Dom commonly refers to a "Daddy Dominant". The BDSM world commonly lays claim to this personality.
Although a Daddy Dom is a dominant figure in a woman's life (sometimes a male will also have a Daddy Dom) not all Doms are Daddies. A Daddy Dom can be, but is not always about, age play. Daddy describes the feeling of comfort, security and guidance that a Daddy Dom provides, and sexual behaviour is often separate from the relationship of every day power exchange that a Daddy Dom provides.
