Depends on the size of the deek.
From experience. . . .
Short deeks so well when I
sit or ride them. Just do as I like.
Doggy is the best for short beef patties.
Never missionary please. . . you will never feel it.
Long Dong Gongers. . . .
back only please. . . for ultimate damage control. Never doggy or horsy. . . if you are not built to take sure an object. . . or "
rock-a-bye baby" or
"carry me daddy". Not fat pussies allowed in this matter. Show don spoil be that.

But my favorite is
knees to head position for maximum penetration and
"hammering".

Every where go just open whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa. And the guy can scratch all corners.

Missionary is only for lazy, fat people or the boringly religious. Of which I am not.
between, you asked us to vote. . . where is the poll boothe?
