I enjoy being called "Daddy" during sex, mostly due to the power dynamics. You see, once when I was a much younger man - probably too young - I was having a rather terrible day and started crying, and my father said to me "I'll give you something to cry about" then fucked me in the ass. I enjoy imagining every woman who calls me Daddy is my Dad and I'm fucking his ass as an act of sexy vengeance. Anyway, it's important to remember everyone's different.
