I don't know whether this will depress you or reassure you, but after 32 years flying I'm still nervous on every flight.
And yet I couldn't do without it and will never give up until I have to.
But then I tell myself that logically, flying is a fundamentally scary business and nerves are therefore hardly surprising.
To my mind the uber cool Sky Gods are either bull!!!!ting or have some intrinsic personality defect, which would make me even more apprehensive about flying with them rather than just on my own or with a non pilot.
On the other hand, as has been remarked, repeated exposure definitely lessens the fear, and to be fair, I suppose that instructors, or professional pilots flying on a daily basis etc, may eventually become immune to a degree.
But then on the other hand again, perhaps a few nerves are a good thing....
