This position is supposed to be good for a man who has a
shorter penis. If you have a short penis and you enjoy this position, you should tell everyone "I have a short penis and the second posture of the perfumed garden worked well for me". That way other men with short penises will hear about it. The word will spread fast and women all over the world will experience more satisfaction.
If you don't have a short penis you might want to get your girlfriend an air bag for her cervix! Get ready to drill for oil.
