Posture
that adjusts the whole physical system is one of the eight therapeutic
sex postures listed in 'Secrets of Plain Girl.' To achieve this
benefit, the woman lies on her back, with both legs folded under
her feet. The man leans over her with his legs apart and mounts
her inserting his Weapon. He should give her exactly eighty-one
strokes of love. This method will strengthen his bones and vitalize
his whole being. Furthermore, it effictively cures sexual problems
of the woman. It should be practiced nine times daily for a
period of nine days in succession. (Note: 81 is 9x 9)
