Spooning in bed - Where is the best placement of the "big spoon's" arm/hand?

[DoctorDoctor 1,391]

Just curious on persons acting as the "big spoon" - Where is the best place to place the top arm/hand?

I'd like opinions from those acting as the "big spoon" and also those acting as the "smaller spoon" on where they prefer (or secretly wish) the big spoon's arm/hand rests.

I never know where to place my arm/hand that is best for both parties.
