Timberwolf, my friend, you are never too young to be a Daddy! I'm 27 and my BF is 45, and he calls me "Mommy" all the time. Well, not *all* the time. :-) But it works.

I agree that the Daddy/Mommy stuff is not at all about actual parents, with whom each of us have very healthy relationships. For me, it means "big, strong, gentle man who takes care of me and loves me and shows me lots of affection." Daddy is a good word for it.
