Very few girls know how to give good deep throat blowjob without puking.
Even less girls know how to make good bacon sandwich.
Even less know how to roll joint without fucking it up.
So in a word.
Yes. 
Very few men don't get bored of the same pussy after a while, no matter how perfect she is.
Even less men care about the great qualities of their dream girl after they reach a brother/sister/dad/mom level depth in knowing each other.
Even less care to find new ways to be passionate when you have all the above in your every day life.
So in short, what you described is unlikely to be enough
