This picture below shows a building that is topped by a structure that is commonly referred to as an “Onion Dome”.
An “Onion Dome” looks like the head of a penis.
The next picture highlights the similarity between an Onion Dome and the head of a penis.
There is a bulge around the base of the Onion Dome like the bulge around the head of a penis,
and the distance from the bulge at the base of the Onion Dome to it’s peak has approximately the same ratio as the distance from the bulge at the base of the penis to the top of the penis.
There is no equivalent of the ball above the Onion Dome in the penis.
So why was the ball added above the Onion Dome if the Onion Dome is really based on the penis? Was it simply an artistic addition? Perhaps to make the Onion Dome look less like a penis?
Does the presence of the ball above the Onion Dome mean the Onion Dome is not based on the penis?
The author believes the ball on top of the Onion Dome was put there because it is a way of representing how the sex act works on the penis.
That may sound odd because most people probably think that friction on the penis caused by rubbing is the only process taking place when a penis is stimulated.
That is not true.
Stimulation of the penis produces what might be called a “force ball” that travels along the center of the penis when it is stimulated. It is the opinion of the author that the small ball on top of the Onion Dome was put there to show that the people who designed the Onion Dome knew that a force ball traveled along the length of the penis when it is stimulated.
