Posture
that strengthens the bones is one of the eight therapeutic sex
postures listed in 'Secrets of Plain Girl.' To achieve this
benefit, the woman lies on her side with her left knee uppermost
and bent. She should stretch out her right leg. The man lies
on top of her, resting his weight on his arms and legs. Inserting
his Weapon, he should give exactly forty-five strokes of love.
This method harmonizes the joints of the man and at the same
time cures any congestion in the body of the woman. It should
be practiced five times daily for a period of ten days. (Note:
45 is 5 x 9)
