"What do you like to be called?"
Yup. That's right.
I wish I could use it, but.... I want my heroine to be the one with the Daddy complex. She didn't *have* a father or a father-figure really, so it's not..... wrong to her. She grew up wishing she had a "Daddy", big, strong, protector... As she got older, she wanted the same things, only from the man she wanted to fuck. Realising your daddy image is sexy hot is..... well depending how your bent, it can just be damn convenient. Getting a man to play daddy for you, that's harder.
