New rider, my first guess would be that you are all tensed up. The small muscles feel it first. You're probably flexing your toes too, trying to claw into the board. It'll come eventually anyway, but you could speed things along by consciously trying to relax and "be the board" instead of trying to control reality by sheer concentration and force of will.
I told my kids, "Someday, you'll have kids of your own." One of them said, "So will you."
