I used to think this was strange but getting used to it. My current SB does this but only in the throes of passion! I take it as a sign of affection and respect.. interested to hear what others think.

My SB knows I love it.So whenever she asks for money she makes sure to call me that

Some girls love calling their SD daddy and being called baby or little girl in return.  I do love it!  But others think it's creepy, so ymmv!

I don't have kids and I like to think that if I had a daughter I would never be interested in doing anything incestuous.

It could be role play incest, but I think most chicks view a "daddy" as a protector.  She's going to obey you and please you.  In exchange you are going to kill the dangerous brontosaurus and bring home the meat.  These are the basic evolutionary roles between the (there are only two) genders.

that brontosaurus were somewhat docile herbivores and lived 100 million years before the appearance of humans but that's OK - this is afterall, the dinosaur Daddy forum   LOL

Are you calling Fred Flintstone a liar?

I thought Betty Rubble was kinda hot.
