Is it normal i like to call my fiancee daddy, he's 49 & i 29?

Normal and one of the more common kinks.

A 20 year difference is nothing.
People get married with a 30 +++ year difference.
Anna Nicole Smith was in her 20's and she married a billionaire tycoon who was in his 90's.
Granted , she married him for his money.

that's so hot I would love to have a baby girl to play with, where can I find these young hotties such as yourself! lol

You like sex with your daddy? Get your head examined.

Why

Doesn't sound all that unusual to me.

At the very least, I hope he's rich.

Sounds like there's more than an element of Oedipus Complex going on here and the fact the guy you call 'daddy' is old enough to be just that, gives more emphasis to this suspicion.

Only you can know to what extent this is the case because those affected by this attraction are almost always fully aware of it.

I'm sure many married women are familiar with the habit of calling their partner 'daddy', as it applies to the father of their children. But to refer to him as 'my daddy', as you're doing, puts a whole different spin on it which cannot be said to be normal in the broader context of what is normal, though it may be deemed normal for you.

But, hey, if you're both happy with this terminology then where's the harm? Although I would urge you to be a little circumspect about when and where you use it. Because such talk in public is sure to result in strange looks and more than a few whispered exchanges which will most likely include the word 'weird' and others too unkind to mention.

Its normal.

Gross.

What do you call your dad? Honey.

when he's spanks your ass does he ask you "who's your daddy?"

Ew.
