You cannot feel a (uniform) gravitational "force" (i.e. field). If a
gravitational force is the only force acting on you, you feel
weightless. This causes no end of confusion to students in elementary
classes, and I have seen teachers with Ph.D's make a total shambles of
this.
The only exception would be an extremely non-uniform gravitional field
as in falling towards the singularity of a black hole. In that case, the
weaker field at your head as compared with your feet, causes you to be
pulled apart by tidal forces.
